doc_alias - The Rust Unstable Book

# `doc_alias`

The tracking issue for this feature is: #50146

You can add alias(es) to an item when using the `rustdoc` search through the `doc(alias)` attribute. Example:

    #![allow(unused)]
    #![feature(doc_alias)]

    fn main() {
    #[doc(alias = "x")]
    #[doc(alias = "big")]
    pub struct BigX;
    }

Then, when looking for it through the `rustdoc` search, if you enter "x" or "big", search will show the `BigX` struct first.

Note that this feature is currently hidden behind the `feature(doc_alias)` gate.
