Struct rustc_trait_selection::traits::PendingPredicateObligation [−][src]
pub struct PendingPredicateObligation<'tcx> {
pub obligation: PredicateObligation<'tcx>,
pub stalled_on: Vec<TyOrConstInferVar<'tcx>>,
}
Fields
obligation: PredicateObligation<'tcx>
stalled_on: Vec<TyOrConstInferVar<'tcx>>
Trait Implementations
type CacheKey = ParamEnvAnd<'tcx, Predicate<'tcx>>
type CacheKey = ParamEnvAnd<'tcx, Predicate<'tcx>>
Note that we include both the ParamEnv
and the Predicate
,
as the ParamEnv
can influence whether fulfillment succeeds
or fails.
Converts this ForestObligation
suitable for use as a cache key.
If two distinct ForestObligations
s return the same cache key,
then it must be sound to use the result of processing one obligation
(e.g. success for error) for the other obligation Read more
