+COMMANDS                                                       *rust-commands*
+
+: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.
+
+: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/"
+
+: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.

+MAPPINGS                                                       *rust-mappings*
+
+This plugin defines mappings for |[[| and |]]| to support hanging indents.
+
+It also has a few other mappings:
+
+							*rust_<D-r>*
+<D-r>			Executes |:RustRun| with no arguments.
+			Note: This binding is only available in MacVim.
+
+							*rust_<D-R>*
+<D-R>			Populates the command line with |:RustRun|! using the
+			arguments given to the last invocation, but does not
+			execute it.
+			Note: This binding is only available in MacVim.
