Expand description

Struct returned by split().

Fields§

§parent_args: <I as Interner>::GenericArgsSlice

This is the args of the typeck root.

§closure_kind_ty: <I as Interner>::Ty

Represents the maximum calling capability of the closure.

§closure_sig_as_fn_ptr_ty: <I as Interner>::Ty

Captures the closure’s signature. This closure signature is “tupled”, and thus has a peculiar signature of extern "rust-call" fn((Args, ...)) -> Ty.

§tupled_upvars_ty: <I as Interner>::Ty

The upvars captured by the closure. Remains an inference variable until the upvar analysis, which happens late in HIR typeck.
