Trait Implementations§

Source§

impl PersistedStore for FileStore

Source§

type Error = FileStoreError

Source§

fn stored_len( &self, region: SnapshotRegion, ) -> Result<Option<usize>, <FileStore as PersistedStore>::Error>

Source§

fn load<'b>( &self, region: SnapshotRegion, buf: &'b mut [u8], ) -> Result<Option<&'b [u8]>, <FileStore as PersistedStore>::Error>

A buf shorter than the stored snapshot is the impl’s error, never a silent truncation.
Source§

fn store( &mut self, region: SnapshotRegion, snapshot: &[u8], ) -> Result<(), <FileStore as PersistedStore>::Error>

Source§

fn remove( &mut self, region: SnapshotRegion, ) -> Result<Removal, <FileStore as PersistedStore>::Error>
