Expand description

Represents a trait method or associated constant or type

Variants

`Const(&'hir Ty<'hir>, Option<BodyId>)`

An associated constant with an optional value (otherwise impls must contain a value).

`Fn(FnSig<'hir>, TraitFn<'hir>)`

An associated function with an optional body.

`Type(GenericBounds<'hir>, Option<&'hir Ty<'hir>>)`

An associated type with (possibly empty) bounds and optional concrete type.
