Struct rustc_hir::TypeBinding

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(...),
}

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.
