Struct rustc_hir_analysis::bounds::Bounds
source · pub(crate) struct Bounds<'tcx> {
clauses: Vec<(Clause<'tcx>, Span)>,
effects_min_tys: FxIndexMap<Ty<'tcx>, Span>,
}
Expand description
Collects together a list of type bounds. These lists of bounds occur in many places in Rust’s syntax:
trait Foo: Bar + Baz { }
^^^^^^^^^ supertrait list bounding the `Self` type parameter
fn foo<T: Bar + Baz>() { }
^^^^^^^^^ bounding the type parameter `T`
impl dyn Bar + Baz
^^^^^^^^^ bounding the type-erased dynamic type
Our representation is a bit mixed here – in some cases, we
include the self type (e.g., trait_bounds
) but in others we do not

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.
