Trait Implementations

impl CanvasPersistenceStore for MemoryCanvasPersistenceStore

type Error = Infallible

fn load_checkpoint(&self) -> Result<Option<CanvasCheckpoint>, Self::Error>

fn save_checkpoint( &mut self, checkpoint: CanvasCheckpoint, ) -> Result<(), Self::Error>

fn append_log_entry(&mut self, entry: CanvasLogEntry) -> Result<(), Self::Error>

fn load_log_entries( &self, after_sequence: u64, ) -> Result<Vec<CanvasLogEntry>, Self::Error>

fn compact_log_entries( &mut self, through_sequence: u64, ) -> Result<(), Self::Error>

impl Clone for MemoryCanvasPersistenceStore

fn clone(&self) -> MemoryCanvasPersistenceStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryCanvasPersistenceStore

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

Formats the value using the given formatter.

impl Default for MemoryCanvasPersistenceStore

fn default() -> MemoryCanvasPersistenceStore

Returns the “default value” for a type.

impl PartialEq for MemoryCanvasPersistenceStore

fn eq(&self, other: &MemoryCanvasPersistenceStore) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
