INTRODUCTION *rust-intro*
|
|
|
|
This plugin provides syntax and supporting functionality for the Rust
|
|
filetype. It requires Vim 8 or higher for full functionality. Some commands
|
|
will not work on earlier versions.
|
|
|
|
==============================================================================
|
|
SETTINGS *rust-settings*
|
|
|
|
This plugin has a few variables you can define in your vimrc that change the
|
|
behavior of the plugin.
|
|
|
|
Some variables can be set buffer local (`:b` prefix), and the buffer local
|
|
will take precedence over the global `g:` counterpart.
|
|
|
|
*g:rustc_path*
|
|
g:rustc_path~
|
|
Set this option to the path to rustc for use in the |:RustRun| and
|
|
|:RustExpand| commands. If unset, "rustc" will be located in $PATH: >
|
|
let g:rustc_path = $HOME."/bin/rustc"
|
|
<
|
|
|
|
*g:rustc_makeprg_no_percent*
|
|
g:rustc_makeprg_no_percent~
|
|
Set this option to 1 to have 'makeprg' default to "rustc" instead of
|
|
"rustc %": >
|
|
let g:rustc_makeprg_no_percent = 1
|
|
<
|
|
|
|
*g:rust_conceal*
|
|
g:rust_conceal~
|
|
Set this option to turn on the basic |conceal| support: >
|
|
let g:rust_conceal = 1
|
|
<
|
|
|
|
*g:rust_conceal_mod_path*
|
|
g:rust_conceal_mod_path~
|
|
Set this option to turn on |conceal| for the path connecting token
|
|
"::": >
|
|
let g:rust_conceal_mod_path = 1
|
|
<
|
|
|
|
*g:rust_conceal_pub*
|
|
g:rust_conceal_pub~
|
|
Set this option to turn on |conceal| for the "pub" token: >
|
|
let g:rust_conceal_pub = 1
|
|
<
|
|
|
|
*g:rust_recommended_style*
|
|
g:rust_recommended_style~
|
|
Set this option to enable vim indentation and textwidth settings to
|
|
conform to style conventions of the rust standard library (i.e. use 4
|
|
spaces for indents and sets 'textwidth' to 99). This option is enabled
|
|
by default. To disable it: >
|
|
let g:rust_recommended_style = 0
|
|
<
|
|
|
|
*g:rust_fold*
|
|
g:rust_fold~
|
|
Set this option to turn on |folding|: >
|
|
let g:rust_fold = 1
|
|
<
|
|
Value Effect ~
|
|
0 No folding
|
|
1 Braced blocks are folded. All folds are open by
|
|
default.
|
|
2 Braced blocks are folded. 'foldlevel' is left at the
|
|
global value (all folds are closed by default).
|
|
|
|
*g:rust_bang_comment_leader*
|
|
g:rust_bang_comment_leader~
|
|
Set this option to 1 to preserve the leader on multi-line doc comments
|
|
using the /*! syntax: >
|
|
let g:rust_bang_comment_leader = 1
|
|
<
|
|
|
|
*g:rust_use_custom_ctags_defs*
|
|
g:rust_use_custom_ctags_defs~
|
|
Set this option to 1 if you have customized ctags definitions for Rust
|
|
and do not wish for those included with rust.vim to be used: >
|
|
let g:rust_use_custom_ctags_defs = 1
|
|
<
|
|
|
|
NOTE: rust.vim's built-in definitions are only used for the Tagbar Vim
|
|
plugin, if you have it installed, AND if Universal Ctags is not
|
|
detected. This is because Universal Ctags already has built-in
|
|
support for Rust when used with Tagbar.
|
|
|
|
Also, note that when using ctags other than Universal Ctags, it is not
|
|
automatically used when generating |tags| files that Vim can use to
|
|
navigate to definitions across different source files. Feel free to
|
|
copy `rust.vim/ctags/rust.ctags` into your own `~/.ctags` if you wish
|
|
to generate |tags| files.
|
|
|
|
|
|
*g:ftplugin_rust_source_path*
|
|
g:ftplugin_rust_source_path~
|
|
Set this option to a path that should be prepended to 'path' for Rust
|
|
source files: >
|
|
let g:ftplugin_rust_source_path = $HOME.'/dev/rust'
|
|
<
|
|
|
|
*g:rustfmt_command*
|
|
g:rustfmt_command~
|
|
Set this option to the name of the 'rustfmt' executable in your $PATH. If
|
|
not specified it defaults to 'rustfmt' : >
|
|
let g:rustfmt_command = 'rustfmt'
|
|
<
|
|
*g:rustfmt_autosave*
|
|
g:rustfmt_autosave~
|
|
Set this option to 1 to run |:RustFmt| automatically when saving a
|
|
buffer. If not specified it defaults to 0 : >
|
|
let g:rustfmt_autosave = 0
|
|
<
|
|
There is also a buffer-local b:rustfmt_autosave that can be set for
|
|
the same purpose, and can override the global setting.
|
|
|
|
*g:rustfmt_autosave_if_config_present*
|
|
g:rustfmt_autosave_if_config_present~
|
|
Set this option to 1 to have *b:rustfmt_autosave* be set automatically
|
|
if a `rustfmt.toml` file is present in any parent directly leading to
|
|
the file being edited. If not set, default to 0: >
|
|
let g:rustfmt_autosave_if_config_present = 0
|
|
<
|
|
This is useful to have `rustfmt` only execute on save, on projects
|
|
that have `rustfmt.toml` configuration.
|
|
|
|
There is also a buffer-local b:rustfmt_autosave_if_config_present
|
|
that can be set for the same purpose, which can overrides the global
|
|
setting.
|
|
*g:rustfmt_fail_silently*
|
|
g:rustfmt_fail_silently~
|
|
Set this option to 1 to prevent 'rustfmt' from populating the
|
|
|location-list| with errors. If not specified it defaults to 0: >
|
|
let g:rustfmt_fail_silently = 0
|
|
<
|
|
*g:rustfmt_options*
|
|
g:rustfmt_options~
|
|
Set this option to a string of options to pass to 'rustfmt'. The
|
|
write-mode is already set to 'overwrite'. If not specified it
|
|
defaults to '' : >
|
|
let g:rustfmt_options = ''
|
|
<
|
|
*g:rustfmt_emit_files*
|
|
g:rustfmt_emit_files~
|
|
If not specified rust.vim tries to detect the right parameter to
|
|
pass to rustfmt based on its reported version. Otherwise, it
|
|
determines whether to run rustfmt with '--emit=files' (when 1 is
|
|
provided) instead of '--write-mode=overwrite'. >
|
|
let g:rustfmt_emit_files = 0
|
|
|
|
|
|
*g:rust_playpen_url*
|
|
g:rust_playpen_url~
|
|
Set this option to override the url for the playpen to use: >
|
|
let g:rust_playpen_url = 'https://play.rust-lang.org/'
|
|
<
|
|
|
|
*g:rust_shortener_url*
|
|
g:rust_shortener_url~
|
|
Set this option to override the url for the url shortener: >
|
|
let g:rust_shortener_url = 'https://is.gd/'
|
|
<
|
|
|
|
*g:rust_clip_command*
|
|
g:rust_clip_command~
|
|
Set this option to the command used in your OS to copy the Rust Play
|
|
url to the clipboard: >
|
|
let g:rust_clip_command = 'xclip -selection clipboard'
|
|
<
|
|
|
|
*g:cargo_makeprg_params*
|
|
g:cargo_makeprg_params~
|
|
Set this option to the string of parameters to pass to cargo. If not
|
|
specified it defaults to '$*' : >
|
|
let g:cargo_makeprg_params = 'build'
|
|
<
|
|
|
|
|
|
Integration with Syntastic *rust-syntastic*
|
|
--------------------------
|
|
|
|
This plugin automatically integrates with the Syntastic checker. There are two
|
|
checkers provided: 'rustc', and 'cargo'. The latter invokes 'Cargo' in order to
|
|
build code, and the former delivers a single edited '.rs' file as a compilation
|
|
target directly to the Rust compiler, `rustc`.
|
|
|
|
Because Cargo is almost exclusively being used for building Rust code these
|
|
days, 'cargo' is the default checker. >
|
|
|
|
let g:syntastic_rust_checkers = ['cargo']
|
|
<
|
|
If you would like to change it, you can set `g:syntastic_rust_checkers` to a
|
|
different value.
|
|
*g:rust_cargo_avoid_whole_workspace*
|
|
*b:rust_cargo_avoid_whole_workspace*
|
|
g:rust_cargo_avoid_whole_workspace~
|
|
When editing a crate that is part of a Cargo workspace, and this
|
|
option is set to 1 (the default), then 'cargo' will be executed
|
|
directly in that crate directory instead of in the workspace
|
|
directory. Setting 0 prevents this behavior - however be aware that if
|
|
you are working in large workspace, Cargo commands may take more time,
|
|
plus the Syntastic error list may include all the crates in the
|
|
workspace. >
|
|
let g:rust_cargo_avoid_whole_workspace = 0
|
|
<
|
|
*g:rust_cargo_check_all_targets*
|
|
*b:rust_cargo_check_all_targets*
|
|
g:rust_cargo_check_all_targets~
|
|
When set to 1, the `--all-targets` option will be passed to cargo when
|
|
Syntastic executes it, allowing the linting of all targets under the
|
|
package.
|
|
The default is 0.
|
|
|
|
*g:rust_cargo_check_all_features*
|
|
*b:rust_cargo_check_all_features*
|
|
g:rust_cargo_check_all_features~
|
|
When set to 1, the `--all-features` option will be passed to cargo when
|
|
Syntastic executes it, allowing the linting of all features of the
|
|
package.
|
|
The default is 0.
|
|
|
|
*g:rust_cargo_check_examples*
|
|
*b:rust_cargo_check_examples*
|
|
g:rust_cargo_check_examples~
|
|
When set to 1, the `--examples` option will be passed to cargo when
|
|
Syntastic executes it, to prevent the exclusion of examples from
|
|
linting. The examples are normally under the `examples/` directory of
|
|
the crate.
|
|
The default is 0.
|
|
|
|
*g:rust_cargo_check_tests*
|
|
*b:rust_cargo_check_tests*
|
|
g:rust_cargo_check_tests~
|
|
When set to 1, the `--tests` option will be passed to cargo when
|
|
Syntastic executes it, to prevent the exclusion of tests from linting.
|
|
The tests are normally under the `tests/` directory of the crate.
|
|
The default is 0.
|
|
|
|
*g:rust_cargo_check_benches*
|
|
*b:rust_cargo_check_benches*
|
|
g:rust_cargo_check_benches~
|
|
When set to 1, the `--benches` option will be passed to cargo when
|
|
Syntastic executes it. The benches are normally under the `benches/`
|
|
directory of the crate.
|
|
The default is 0.
|
|
|
|
Integration with auto-pairs *rust-auto-pairs*
|
|
---------------------------
|
|
|
|
This plugin automatically configures the auto-pairs plugin not to duplicate
|
|
single quotes, which are used more often for lifetime annotations than for
|
|
single character literals.
|
|
|
|
*g:rust_keep_autopairs_default*
|
|
g:rust_keep_autopairs_default~
|
|
|
|
Don't override auto-pairs default for the Rust filetype. The default
|
|
is 0.

COMMANDS *rust-commands*
|
|
|
|
Invoking Cargo

|
|
depending on the currently open buffer.
|
|
|
|
Formatting
|
|
----------
|
|
|
|
:RustFmt *:RustFmt*
|
|
Runs |g:rustfmt_command| on the current buffer. If
|
|
|g:rustfmt_options| is set then those will be passed to the
|
|
executable.
|
|
|
|
If |g:rustfmt_fail_silently| is 0 (the default) then it
|
|
will populate the |location-list| with the errors from
|
|
|g:rustfmt_command|. If |g:rustfmt_fail_silently| is set to 1
|
|
then it will not populate the |location-list|.
|
|
|
|
:RustFmtRange *:RustFmtRange*
|
|
Runs |g:rustfmt_command| with selected range. See
|
|
|:RustFmt| for any other information.
|
|
|
|
|
|
Playpen integration
|
|
-------------------
|
|
|
|
:RustPlay *:RustPlay*
|
|
This command will only work if you have web-api.vim installed
|
|
(available at https://github.com/mattn/webapi-vim). It sends the
|
|
current selection, or if nothing is selected, the entirety of the
|
|
current buffer to the Rust playpen, and emits a message with the
|
|
shortened URL to the playpen.
|
|
|
|
|g:rust_playpen_url| is the base URL to the playpen, by default
|
|
"https://play.rust-lang.org/".
|
|
|
|
|g:rust_shortener_url| is the base url for the shorterner, by
|
|
default "https://is.gd/"
|
|
|
|
|g:rust_clip_command| is the command to run to copy the
|
|
playpen url to the clipboard of your system.
|
|
|
|
|
|
Evaluation of a single Rust file
|
|
--------------------------------
|
|
|
|
NOTE: These commands are useful only when working with standalone Rust files,
|
|
which is usually not the case for common Rust development. If you wish to
|
|
building Rust crates from with Vim can should use Vim's make, Syntastic, or
|
|
functionality from other plugins.
|
|
|
|
|
|
:RustRun [args] *:RustRun*
|
|
:RustRun! [rustc-args] [--] [args]
|
|
Compiles and runs the current file. If it has unsaved changes,
|
|
it will be saved first using |:update|. If the current file is
|
|
an unnamed buffer, it will be written to a temporary file
|
|
first. The compiled binary is always placed in a temporary
|
|
directory, but is run from the current directory.
|
|
|
|
The arguments given to |:RustRun| will be passed to the
|
|
compiled binary.
|
|
|
|
If ! is specified, the arguments are passed to rustc instead.
|
|
A "--" argument will separate the rustc arguments from the
|
|
arguments passed to the binary.
|
|
|
|
If |g:rustc_path| is defined, it is used as the path to rustc.
|
|
Otherwise it is assumed rustc can be found in $PATH.
|
|
|
|
:RustExpand [args] *:RustExpand*
|
|
:RustExpand! [TYPE] [args]
|
|
Expands the current file using --pretty and displays the
|
|
results in a new split. If the current file has unsaved
|
|
changes, it will be saved first using |:update|. If the
|
|
current file is an unnamed buffer, it will be written to a
|
|
temporary file first.
|
|
|
|
The arguments given to |:RustExpand| will be passed to rustc.
|
|
This is largely intended for specifying various --cfg
|
|
configurations.
|
|
|
|
If ! is specified, the first argument is the expansion type to
|
|
pass to rustc --pretty. Otherwise it will default to
|
|
"expanded".
|
|
|
|
If |g:rustc_path| is defined, it is used as the path to rustc.
|
|
Otherwise it is assumed rustc can be found in $PATH.
|
|
|
|
:RustEmitIr [args] *:RustEmitIr*
|
|
Compiles the current file to LLVM IR and displays the results
|
|
in a new split. If the current file has unsaved changes, it
|
|
will be saved first using |:update|. If the current file is an
|
|
unnamed buffer, it will be written to a temporary file first.
|
|
|
|
The arguments given to |:RustEmitIr| will be passed to rustc.
|
|
|
|
If |g:rustc_path| is defined, it is used as the path to rustc.
|
|
Otherwise it is assumed rustc can be found in $PATH.
|
|
|
|
:RustEmitAsm [args] *:RustEmitAsm*
|
|
Compiles the current file to assembly and displays the results
|
|
in a new split. If the current file has unsaved changes, it
|
|
will be saved first using |:update|. If the current file is an
|
|
unnamed buffer, it will be written to a temporary file first.
|
|
|
|
The arguments given to |:RustEmitAsm| will be passed to rustc.
|
|
|
|
If |g:rustc_path| is defined, it is used as the path to rustc.
|
|
Otherwise it is assumed rustc can be found in $PATH.
|
|
|
|
|
|
Running test(s)
|
|
---------------
|
|
|
|
:[N]RustTest[!] [options] *:RustTest*
|
|
Runs a test under the cursor when the current buffer is in a
|
|
cargo project with "cargo test" command. If the command did
|
|
not find any test function under the cursor, it stops with an
|
|
error message.
|
|
|
|
When N is given, adjust the size of the new window to N lines
|
|
or columns.
|
|
|
|
When ! is given, runs all tests regardless of current cursor
|
|
position.
|
|
|
|
When [options] is given, it is passed to "cargo" command
|
|
arguments.
|
|
|
|
When the current buffer is outside cargo project, the command
|
|
runs "rustc --test" command instead of "cargo test" as
|
|
fallback. All tests are run regardless of adding ! since there
|
|
is no way to run specific test function with rustc. [options]
|
|
is passed to "rustc" command arguments in the case.
|
|
|
|
Takes optional modifiers (see |<mods>|): >

rust.vim Debugging
|
|
------------------
|
|
|
|
:RustInfo *:RustInfo*
|
|
Emits debugging info of the Vim Rust plugin.
|
|
|
|
:RustInfoToClipboard *:RustInfoClipboard*
|
|
Saves debugging info of the Vim Rust plugin to the default
|
|
register.
|
|
|
|
:RustInfoToFile [filename] *:RustInfoToFile*
|
|
Saves debugging info of the Vim Rust plugin to the the given
|
|
file, overwritting it.
|
