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

Performs copy-assignment from source.

impl<N: Network> CommitteeStorage<N> for CommitteeMemory<N>

fn open<S: Clone + Into<StorageMode>>(storage: S) -> Result<Self>

fn start_atomic(&self)

Starts an atomic batch write operation.

fn is_atomic_in_progress(&self) -> bool
