Trait Implementations

fn normalize_projection_type(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>,
    _param_env: ParamEnv<'tcx>,
    projection_ty: ProjectionTy<'tcx>,
    _cause: ObligationCause<'tcx>
) -> Ty<'tcx>

fn register_predicate_obligation(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>,
    obligation: PredicateObligation<'tcx>
)

fn select_all_or_error(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>
) -> Result<(), Vec<FulfillmentError<'tcx>>>

fn select_where_possible(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>
) -> Result<(), Vec<FulfillmentError<'tcx>>>

fn pending_obligations(&self) -> Vec<PredicateObligation<'tcx>>

fn relationships(&mut self) -> &mut FxHashMap<TyVid, FoundRelationships>

fn register_bound(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>,
    param_env: ParamEnv<'tcx>,
    ty: &'tcx TyS<'tcx>,
    def_id: DefId,
    cause: ObligationCause<'tcx>
)

Requires that ty must implement the trait with def_id in the given environment. This trait must not have any type parameters (except for Self).

fn select_all_with_constness_or_error(
    &mut self,
    infcx: &InferCtxt<'_, 'tcx>,

fn select_with_constness_where_possible(
    &mut self,

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.
