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(&self, queue: LogQueue, bytes: &[u8]) -> Result<FileBlockHandle>

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

source

fn maybe_sync(&self, queue: LogQueue, force: bool) -> Result<()>

Hints it to synchronize buffered writes. The synchronization is mandotory when sync is true. Read more

source

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

Returns the smallest and largest file sequence number of the specified log queue. Read more

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 up to 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.
