Struct rustc_middle::traits::ImplSourceUserDefinedData
source · pub struct ImplSourceUserDefinedData<'tcx, N> {
pub impl_def_id: DefId,
pub substs: SubstsRef<'tcx>,
pub nested: Vec<N>,
}
Expand description
Identifies a particular impl in the source, along with a set of
substitutions from the impl’s type/lifetime parameters. The
nested
vector corresponds to the nested obligations attached to
the impl’s type parameters.
The type parameter N
indicates the type used for “nested
obligations” that are required by the impl. During type-check, this
is Obligation
, as one might expect. During codegen, however, this
is ()
, because codegen only requires a shallow resolution of an
impl, and nested obligations are satisfied later.
Fields
impl_def_id: DefId
substs: SubstsRef<'tcx>
nested: Vec<N>

attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
