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>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for UpvarSubsts<'tcx>

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