Struct rustc_infer::infer::opaque_types::OpaqueTypeDecl
source · pub struct OpaqueTypeDecl<'tcx> {
pub hidden_type: OpaqueHiddenType<'tcx>,
}
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§
The hidden types that have been inferred for this opaque type.
There can be multiple, but they are all lub
ed together at the end
to obtain the canonical hidden 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.
