/* private fields */

Fields§
§args: &'tcx RawList<(), GenericArg<'tcx>>
The parameters of the associated or opaque type.
For a projection, these are the generic parameters for the trait and the GAT parameters, if there are any.
For an inherent projection, they consist of the self type and the GAT parameters, if there are any.
For RPIT the generic parameters are for the generics of the function, while for TAIT it is used for the generic parameters of the alias.
def_id: DefId
The DefId
of the TraitItem
or ImplItem
for the associated type N
depending on whether
this is a projection or an inherent projection or the DefId
of the OpaqueType
item if
this is an opaque.
During codegen, interner.type_of(def_id)
can be used to get the type of the
underlying type if the type is an opaque.
Note that if this is an associated type, this is not the DefId
of the
TraitRef
containing this associated type, which is in interner.associated_item(def_id).container
,
aka. interner.parent(def_id)
.

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.
