Struct rustc_hir::TypeBinding

source ·
pub struct TypeBinding<'hir> {
    pub hir_id: HirId,
    pub ident: Ident,

    pub kind: TypeBindingKind<'hir>,
    pub span: Span,
}
Expand description

Bind a type to an associated type (i.e., A = Foo).

Bindings like A: Debug are represented as a special type A = $::Debug that is understood by the astconv code.

FIXME(alexreg): why have a separate type for the binding case, wouldn’t it be better to make the ty field an enum like the following?

enum TypeBindingKind {
   Equals(...),
   Binding(...),
}
