Implementations

impl<'tcx, 'a> GeneratorData<'tcx, 'a>

fn try_get_upvar_span<F>( &self, infer_context: &InferCtxt<'tcx>, generator_did: DefId, ty_matches: F ) -> Option<GeneratorInteriorOrUpvar>where F: Fn(Binder<'tcx, Ty<'tcx>>) -> bool,

Try to get information about variables captured by the generator that matches a type we are looking for with ty_matches function. We uses it to find upvar which causes a failure to meet an obligation

fn get_from_await_ty<F>( &self, visitor: AwaitsVisitor, hir: Map<'tcx>, ty_matches: F ) -> Option<Span>where F: Fn(Binder<'tcx, Ty<'tcx>>) -> bool,

Try to get the span of a type being awaited on that matches the type we are looking with the ty_matches function. We uses it to find awaited type which causes a failure to meet an obligation

Trait Implementations

impl<'tcx, 'a> Debug for GeneratorData<'tcx, 'a>

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

Formats the value using the given formatter.

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.
