Expand description
See docs for explanation of how each argument is used.
See CoroutineClosureSignature
for how these arguments are put together
to make a callable ty::FnSig
suitable for typeck and borrowck.
Fields§
§parent_args: I::GenericArgsSlice
This is the args of the typeck root.
closure_kind_ty: I::Ty
Represents the maximum calling capability of the closure.
signature_parts_ty: I::Ty
Represents all of the relevant parts of the coroutine returned by this
coroutine-closure. This signature parts type will have the general
shape of fn(tupled_inputs, resume_ty) -> (return_ty, yield_ty)
, where
resume_ty
, return_ty
, and yield_ty
are the respective types for the
coroutine returned by the coroutine-closure.
Use coroutine_closure_sig
to break up this type rather than using it
yourself.
tupled_upvars_ty: I::Ty
The upvars captured by the closure. Remains an inference variable until the upvar analysis, which happens late in HIR typeck.
coroutine_captures_by_ref_ty: I::Ty
a function pointer that has the shape for<'env> fn() -> (&'env T, ...)
.
This allows us to represent the binder of the self-captures of the closure.
For example, if the coroutine returned by the closure borrows String
from the closure’s upvars, this will be for<'env> fn() -> (&'env String,)
,
while the tupled_upvars_ty
, representing the by-move version of the same
captures, will be (String,)
.
coroutine_witness_ty: I::Ty
Witness type returned by the generator produced by this coroutine-closure.

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
