Michael Howell	12dc24f460	rustdoc-search: simplify rules for generics and type params ... This commit is a response to feedback on the displayed type signatures results, by making generics act stricter. Generics are tightened by making order significant. This means `Vec<Allocator>` now matches only with a true vector of allocators, instead of matching the second type param. It also makes unboxing within generics stricter, so `Result<A, B>` only matches if `B` is in the error type and `A` is in the success type. The top level of the function search is unaffected.

Michael Howell	7b926555b7	rustdoc-search: add search query syntax Fn(T) -> U ... This is implemented, in addition to the ML-style one, because Rust does it. If we don't, we'll never hear the end of it. This commit also refactors some duplicate parts of the parser into a dedicated function.	2024-03-11 22:27:22 -07:00
Michael Howell	7f427f86bd	rustdoc-search: parse and search with ML-style HOF ... Option::map, for example, looks like this: option<t>, (t -> u) -> option<u> This syntax searches all of the HOFs in Rust: traits Fn, FnOnce, and FnMut, and bare fn primitives.	2024-03-11 21:22:03 -07:00
