a " sub level type" , and 0-N " parameters" . And they' re all strings.
Strings everywhere. Strings mean typos. Rust has type safety. We should
use types!< / p >

your typos.< / p >

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

Accepted types are: < code > fn< / code > , < code > mod< / code > ,
< code > struct< / code > , < code > enum< / code > ,
< code > trait< / code > , < code > type< / code > , < code > macro< / code > ,
and < code > const< / code > .
< / p >
< p >
Search functions by type signature (e.g.
< code > vec -> usize< / code > or < code > * -> vec< / code > )
