"WebbSearch 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) " - Sm4 block size
