rman - Search the Rust Documentation offline

Want to search your local offline rust std documentation, with a quick command from your terminal?

Preparation:

Download the rust documentation:

$ rustup component add rust-docs

Setup a bash function (you might need to replace firefox with your browser):

function rman() { 
    firefox "file://$(rustc --print sysroot)/share/doc/rust/html/std/index.html?search=$@"
}

Fire up your browser with the search window from your terminal:

$ rman MaybeUnit

Ok… it’s not man and apropos … but good enough for now.
