Expand description

A PipeLog implementation that stores data in filesystem.

Trait Implementations§

Source §

impl<F: FileSystem> PipeLog for DualPipes<F>

Source §

fn read_bytes(&self, handle: FileBlockHandle) -> Result<Vec<u8>>

Reads some bytes from the specified position.

Source §

fn append<T: ReactiveBytes + ?Sized>( &self, queue: LogQueue, bytes: &mut T, ) -> Result<FileBlockHandle>

Appends some bytes to the specified log queue. Returns file position of the written bytes.

Source §

fn sync(&self, queue: LogQueue) -> Result<()>

Synchronizes all buffered writes. Read more

Source §

fn file_span(&self, queue: LogQueue) -> (FileSeq, FileSeq)

Returns the smallest and largest file sequence number, still in use, of the specified log queue.

Source §

fn total_size(&self, queue: LogQueue) -> usize

Returns total size of the specified log queue.

Source §

fn rotate(&self, queue: LogQueue) -> Result<()>

Rotates a new log file for the specified log queue. Read more

Source §

fn purge_to(&self, file_id: FileId) -> Result<usize>

Deletes all log files smaller than the specified file ID. The scope is limited to the log queue of file_id. Read more

Source §

fn file_at(&self, queue: LogQueue, position: f64) -> FileSeq

Returns the oldest file ID that is newer than position% of all files.
