Trait Implementations

impl Debug for SimpleOpHeadsStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl OpHeadsStore for SimpleOpHeadsStore

fn as_any(&self) -> &dyn Any

fn name(&self) -> &str

fn update_op_heads( &self, old_ids: &[OperationId], new_id: &OperationId, ) -> Result<(), OpHeadsStoreError>

Remove the old op heads and add the new one.

fn get_op_heads(&self) -> Result<Vec<OperationId>, OpHeadsStoreError>

fn lock(&self) -> Result<Box<dyn OpHeadsStoreLock + '_>, OpHeadsStoreError>

Optionally takes a lock on the op heads store. The purpose of the lock is to prevent concurrent processes from resolving the same divergent operations. It is not needed for correctness; implementations are free to return a type that doesn’t hold a lock.
