Expand description
Represents an item declaration within a trait declaration, possibly including a default implementation. A trait item is either required (meaning it doesn’t have an implementation, just a signature) or provided (meaning it has a default implementation).
Fields§
§ident: Ident
§owner_id: OwnerId
§generics: &'hir Generics<'hir>
§kind: TraitItemKind<'hir>
§span: Span

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
