Expand description

Children of a given impl, grouped into blanket/non-blanket varieties as is done in TraitDef.

Fields§

§non_blanket_impls: IndexMap<SimplifiedType, Vec<DefId, Global>, BuildHasherDefault<FxHasher>>

Impls of the trait.

§blanket_impls: Vec<DefId, Global>

Blanket impls associated with the trait.

Trait Implementations§

source§

impl<'tcx> ChildrenExt<'tcx> for Children

source§

fn insert_blindly(&mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId)

Insert an impl into this set of children without comparing to any existing impls.

source§

fn remove_existing(&mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId)

Removes an impl from this set of children. Used when replacing an impl with a parent. The impl must be present in the list of children already.

source§

fn insert( &mut self, tcx: TyCtxt<'tcx>, impl_def_id: DefId, simplified_self: Option<SimplifiedType>, overlap_mode: OverlapMode ) -> Result<Inserted<'tcx>, OverlapError<'tcx>>

Attempt to insert an impl into this set of children, while comparing for specialization relationships.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

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.
