Search Tricks

Prefix searches with a type followed by a colon (e.g., fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g., vec -> usize or * -> vec)

Search multiple things at once by splitting your query with comma (e.g., str,u8 or String,struct:Vec,test)

You can look for items with an exact name by putting double quotes around your request: "string"

Look for items inside another one by searching for a path: vec::Vec
