Struct rustc_data_structures::unify::Snapshot

source · 
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.

impl<'a, T> Captures<'a> for Twhere T: ?Sized,

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
