fast-rustc-ap-rustc_attr-1.0.0 doesn't have any documentation.

Functions and types dealing with attributes and meta items.

FIXME(Centril): For now being, much of the logic is still in rustc_ast::attr. The goal is to move the definition of MetaItem and things that don't need to be in syntax to this crate.
