Implementations

impl<'tcx> UpvarSubsts<'tcx>

pub fn upvar_tys(self) -> impl Iterator<Item = Ty<'tcx>> + 'tcx

Returns an iterator over the list of types of captured paths by the closure/generator. In case there was a type error in figuring out the types of the captured path, an empty iterator is returned.

pub fn tupled_upvars_ty(self) -> Ty<'tcx>

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
