Trait Implementations

impl<K: Clone, V: Clone> Clone for UndoLog<K, V>

fn clone(&self) -> UndoLog<K, V>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K, V> Rollback<UndoLog<K, V>> for FxHashMap<K, V>where K: Eq + Hash,

fn reverse(&mut self, undo: UndoLog<K, V>)

impl<K, V, M, L> Rollback<UndoLog<K, V>> for SnapshotMap<K, V, M, L>where K: Eq + Hash, M: Rollback<UndoLog<K, V>>,

fn reverse(&mut self, undo: UndoLog<K, V>)

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.
