Array(Ty<'tcx>)
The type is of the element
Tuple
Adt(DefId, VariantIdx, GenericArgsRef<'tcx>, Option<UserTypeAnnotationIndex>, Option<FieldIdx>)
The second field is the variant index. It’s equal to 0 for struct
and union expressions. The last field is the
active field number and is present only for union expressions
– e.g., for a union expression SomeUnion { c: .. }
, the
active field index would identity the field c

Coroutine(DefId, GenericArgsRef<'tcx>)

RawPtr(Ty<'tcx>, Mutability)
Construct a raw pointer from the data pointer and metadata.
The Ty
here is the type of the pointee, not the pointer itself.
The Mutability
indicates whether this produces a *const
or *mut
.
The Rvalue::Aggregate
operands for thus must be
- A raw pointer of matching mutability with any
core::ptr::Thin
pointee - A value of the appropriate
core::ptr::Pointee::Metadata
type
Both operands must always be included, even the unit value if this is
creating a thin pointer. If you’re just converting between thin pointers,
you may want an Rvalue::Cast
with CastKind::PtrToPtr
instead.
