pub trait Rollback<U> {
    // Required method

Required Methods§

fn reverse(&mut self, undo: U)

Implementations on Foreign Types§

impl Rollback<UndoLog> for Vec<<D as SnapshotVecDelegate>::Value>

fn reverse(&mut self, undo: UndoLog)

impl<T, U> Rollback for &mut T

fn reverse(&mut self, undo: U)
