Add `BoundKind` in `visit_param_bounds` to check questions in bounds From the FIXME in the impl of `AstValidator`. Better bound checks by adding `BoundCtxt` type parameter to `visit_param_bound` cc `@ecstatic-morse`
The rustc_ast crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
