#Example Usage

Before running rusty-man, make sure that you generated the documentation with cargo doc:

$ cd rusty-man && cargo doc

Then you can open the documentation for an item:

$ rusty-man kuchiki::NodeRef

You don’t have to specificy the full item name:

$ rusty-man NodeRef

If the documentation is not placed in ./target/doc or the Rust installation directory, you have to manually set the source path using the -s/--source option:

$ rusty-man --source my/other/crate/target/doc io::Error

If there are multiple matches for the keyword, rusty-man will show you a list of all matching items:

$ rusty-man --source my/other/crate/target/doc u8
Found mulitple matches for u8 – select one of:

[ 0 ] core::u8: The 8-bit unsigned integer type.
[ 1 ] std::u8: The 8-bit unsigned integer type.

> 1

For more usage information, run rusty-man --help.


rusty-man has three viewers (select one with the --viewer option) that determine the output format:

  • plain prints the documentation to the standard output without formatting. This is the default for non-interactive use.
  • rich prints the documentation to the standard output with formatting and optional syntax highlighting. This is the default for interactive use.
  • tui is an interactive terminal interface. You can read the documentation and follow links.


To install rusty-man from source, clone this repository and use cargo to build the project, or use cargo install. See the INSTALL.md file for more information. rusty-man is also available as a package for these distributions:

  • Arch Linux: rusty-man in the Arch User Repository

rusty-man is developed for Unix-like systems. It should run on other platforms too, but with some limitations: The rich and tui viewers uses ANSI escape codes, which are not supported on older Windows versions. If you have trouble running rusty-man on your platform or if you want to help porting rusty-man to other platforms, please let me know.



You can set rusty-man as the keyword program with set keywordprg=rusty-man and then use K to open the documentation for the item under the cursor. If you want to apply this setting for all Rust files, add it to the ftplugin/rust.vim file in your vim runtime directory (e. g. ~/.vim).


Contributions to this project are very welcome! You can contribute by writing code or documentation or by testing. See the CONTRIBUTING.md file for more information.
