pub struct OpaqueTypeDecl<'tcx> {
    pub hidden_type: OpaqueHiddenType<'tcx>,
    pub origin: OpaqueTyOrigin,
}
Expand description

Information about the opaque types whose values we are inferring in this function (these are the impl Trait that appear in the return type).

Fields§

§hidden_type: OpaqueHiddenType<'tcx>

The hidden types that have been inferred for this opaque type. There can be multiple, but they are all lubed together at the end to obtain the canonical hidden type.

§origin: OpaqueTyOrigin

The origin of the opaque 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.
