Struct rustc_data_structures::unify::Snapshot[−][src]

pub struct Snapshot<S> where
    S: UnificationStore,  {
    marker: PhantomData<S>,
    snapshot: <S as UnificationStore>::Snapshot,
}

Expand description

At any time, users may snapshot a unification table. The changes made during the snapshot may either be committed or rolled back.

Fields

marker: PhantomData<S>snapshot: <S as UnificationStore>::Snapshot
