Struct rustc_infer::infer::opaque_types::OpaqueTypeDecl

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

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.

Trait Implementations

impl<'tcx> Clone for OpaqueTypeDecl<'tcx>

fn clone(&self) -> OpaqueTypeDecl<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for OpaqueTypeDecl<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
