Struct chalk_ir::OpaqueTy [−][src]
pub struct OpaqueTy<I: Interner> { pub opaque_ty_id: OpaqueTyId<I>, pub substitution: Substitution<I>, }
Expand description
An opaque type opaque type T<..>: Trait = HiddenTy
.
Fields
opaque_ty_id: OpaqueTyId<I>
The id for the opaque type.
substitution: Substitution<I>
The substitution for the opaque type.
Implementations
Show debug output for the opaque type.
Trait Implementations
The type of value that will be produced once folding is done.
Typically this is Self
, unless Self
contains borrowed
values, in which case owned values are produced (for example,
one can fold over a &T
value where T: Fold
, in which case
you get back a T
, not a &T
). Read more
Apply the given folder folder
to self
; binders
is the
number of binders that are in scope when beginning the
folder. Typically binders
starts as 0, but is adjusted when
we encounter Binders<T>
in the IR or other similar
constructs. Read more
type Interner = I
type Interner = I
The interner associated with the type.
