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>, BuildHasherDefault<FxHasher>>`

Impls of the trait.

§`blanket_impls: Vec<DefId>`

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.

### impl<T> From<T> for T

source§

#### fn from(t: T) -> T

Returns the argument unchanged.

source§

### impl<T, U> Into<U> for T

where U: Into<T>,

§

#### type Error = Infallible

The type returned in the event of a conversion error.
source§

#### fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.
source§

### impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

§

#### type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
source§

#### 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.
