Trait rustc_data_structures::unify::UnificationStoreBase

pub trait UnificationStoreBase: Index<usize, Output = VarValue<Self::Key>> {
    type Key: UnifyKey<Value = Self::Value>;
    type Value: UnifyValue;

    // Required method
    fn len(&self) -> usize;

    // Provided method
    fn tag() -> &'static str { ... }
}

Largely internal trait implemented by the unification table backing store types. The most common such type is InPlace, which indicates a standard, mutable unification table.

Required Associated Types

type Key: UnifyKey<Value = Self::Value>

type Value: UnifyValue

Required Methods

fn len(&self) -> usize

Provided Methods

fn tag() -> &'static str

Object Safety

This trait is not object safe.

Implementors

impl<K, V, L> UnificationStoreBase for InPlace<K, V, L>

where K: UnifyKey, V: VecLike<Delegate<K>>,

type Key = K

type Value = <K as UnifyKey>::Value
