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.

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 +-------------- + +This plug defines very simple shortcuts for invoking Cargo from with Vim. + +:Cargo <args> *:Cargo* + Runs 'cargo' with the provided arguments. + +:Cbuild <args> *:Cbuild* + Shortcut for 'cargo build`. + +:Cclean <args> *:Cclean* + Shortcut for 'cargo clean`. + +:Cdoc <args> *:Cdoc* + Shortcut for 'cargo doc`. + +:Cinit <args> *:Cinit* + Shortcut for 'cargo init`. + +:Crun <args> *:Crun* + Shortcut for 'cargo run`. + +:Ctest <args> *:Ctest* + Shortcut for 'cargo test`. + +:Cupdate <args> *:Cupdate* + Shortcut for 'cargo update`. + +:Cbench <args> *:Cbench* + Shortcut for 'cargo bench`. + +:Csearch <args> *:Csearch* + Shortcut for 'cargo search`. + +:Cpublish <args> *:Cpublish* + Shortcut for 'cargo publish`. + +:Cinstall <args> *:Cinstall* + Shortcut for 'cargo install`. + +:Cruntarget <args> *:Cruntarget* + 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.
