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:
g:rustc_makeprg_no_percent
g:rustc_makeprg_no_percent
Set this option to 1 to have 'makeprg' default to "rustc" instead of
"rustc %":
g:rust_conceal
g:rust_conceal
Set this option to turn on the basic conceal support:
g:rust_conceal_mod_path
g:rust_conceal_mod_path
Set this option to turn on conceal for the path connecting token
"::":
g:rust_conceal_pub
g:rust_conceal_pub
Set this option to turn on conceal for the "pub" token:
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:
g:rust_fold
g:rust_fold
Set this option to turn on folding:
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:
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:
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:
g:rustfmt_command
g:rustfmt_command
Set this option to the name of the 'rustfmt' executable in your $PATH. If
not specified it defaults to 'rustfmt' :
g:rustfmt_autosave
g:rustfmt_autosave
Set this option to 1 to run :RustFmt automatically when saving a
buffer. If not specified it defaults to 0 :
There is also a buffer-local b:rustfmt_autosave that can be set for
the same purpose, and can override the global setting.
g:rustfmt_autosave_if_config_present
g:rustfmt_autosave_if_config_present
Set this option to 1 to have b:rustfmt_autosave be set automatically
if a rustfmt.toml file is present in any parent directly leading to
the file being edited. If not set, default to 0:
This is useful to have rustfmt only execute on save, on projects
that have rustfmt.toml configuration.
There is also a buffer-local b:rustfmt_autosave_if_config_present
that can be set for the same purpose, which can overrides the global
setting.
g:rustfmt_fail_silently
g:rustfmt_fail_silently
Set this option to 1 to prevent 'rustfmt' from populating the
location-list with errors. If not specified it defaults to 0:
g:rustfmt_options
g:rustfmt_options
Set this option to a string of options to pass to 'rustfmt'. The
write-mode is already set to 'overwrite'. If not specified it
defaults to '' :
g:rustfmt_emit_files
g:rustfmt_emit_files
If not specified rust.vim tries to detect the right parameter to
pass to rustfmt based on its reported version. Otherwise, it
determines whether to run rustfmt with '--emit=files' (when 1 is
provided) instead of '--write-mode=overwrite'.
g:rust_playpen_url
g:rust_playpen_url
Set this option to override the url for the playpen to use:
g:rust_shortener_url
g:rust_shortener_url
Set this option to override the url for the url shortener:
g:rust_clip_command
g:rust_clip_command
Set this option to the command used in your OS to copy the Rust Play
url to the clipboard:
g:cargo_makeprg_params
g:cargo_makeprg_params
Set this option to the string of parameters to pass to cargo. If not
specified it defaults to '$*' :
g:cargo_shell_command_runner
g:cargo_shell_command_runner
Set this option to change how to run shell commands for cargo commands
:Cargo, :Cbuild, :Crun, ...
By default, :terminal is used to run shell command in terminal window
asynchronously. But if you prefer :! for running the commands, it can
be specified:
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.
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.
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.

Shortcut for 'cargo run --bin' or 'cargo run --example',
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 given file,
overwriting 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>):
:tab RustTest
:belowright 16RustTest
:leftabove vert 80RustTest
:belowright 16RustTest
:leftabove vert 80RustTest
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 given file,
overwriting it.
