Struct rustc_hir::TypeBinding

source ·
pub struct TypeBinding<'hir> {
    pub hir_id: HirId,
    pub ident: Ident,
    pub gen_args: &'hir GenericArgs<'hir>,
    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(...),
}

Fields

hir_id: HirIdident: Identgen_args: &'hir GenericArgs<'hir>kind: TypeBindingKind<'hir>span: Span

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.
