Trait Implementations§

source§

impl<'tcx> TypeRelatingDelegate<'tcx> for QueryTypeRelatingDelegate<'_, 'tcx>

source§

fn span(&self) -> Span

source§

fn param_env(&self) -> ParamEnv<'tcx>

source§

fn create_next_universe(&mut self) -> UniverseIndex

Creates a new universe index. Used when instantiating placeholders.
source§

fn next_existential_region_var( &mut self, from_forall: bool, _name: Option<Symbol> ) -> Region<'tcx>

Creates a new region variable representing a higher-ranked region that is instantiated existentially. This creates an inference variable, typically. Read more
source§

fn next_placeholder_region( &mut self, placeholder: PlaceholderRegion ) -> Region<'tcx>

Creates a new region variable representing a higher-ranked region that is instantiated universally. This creates a new region placeholder, typically. Read more
source§

fn push_outlives( &mut self, sup: Region<'tcx>, sub: Region<'tcx>, _info: VarianceDiagInfo<'tcx> )

Push a constraint sup: sub – this constraint must be satisfied for the two types to be related. sub and sup may be regions from the type or new variables created through the delegate.
source§

fn forbid_inference_vars() -> bool

Enables some optimizations if we do not expect inference variables in the RHS of the relation.
source§

fn register_obligations(&mut self, obligations: PredicateObligations<'tcx>)
