Implementations

impl<'tcx> UpvarArgs<'tcx>

pub fn upvar_tys(self) -> &'tcx List<Ty<'tcx>>

Returns an iterator over the list of types of captured paths by the closure/coroutine. 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>

impl<'tcx> Clone for UpvarArgs<'tcx>

fn clone(&self) -> UpvarArgs<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx> Debug for UpvarArgs<'tcx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
