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 impl
s 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.

Layout§
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.
