Rust Vim Plugin: :RustEmitIr, :RustEmitAsm, :RustTest, Debugging, and Mappings

`--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>|): >vim :tab RustTest :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. ============================================================================== MAPPINGS *rust-mappings* This plugin defines mappings for |[[| and |]]| to support hanging indents. vim:tw=78:sw=4:noet:ts=8:ft=help:norl:

This section covers several Vim commands for Rust development. `:RustEmitIr` and `:RustEmitAsm` compile the current file to LLVM IR and assembly, respectively, displaying the results in a new split. `:RustTest` runs tests in the current buffer using `cargo test` or `rustc --test`. Additionally, the plugin provides commands for debugging itself (`:RustInfo`, `:RustInfoToClipboard`, `:RustInfoToFile`). Finally, it defines mappings for `[[` and `]]` to support hanging indents.
