Struct FilePersistence 

pub struct FilePersistence {
    path: PathBuf,
    compact_threshold_bytes: Option<u64>,
}

Configures session persistence backed by a CRC-framed journal file.

Build one with new and pass it to ClientBuilder::persistence.

Fields

path: PathBuf

compact_threshold_bytes: Option<u64>

Implementations

impl FilePersistence

pub fn new(path: impl Into<PathBuf>) -> Self

Persists the session to a journal file at path, without automatic compaction.

pub const fn compact_threshold_bytes(self, bytes: u64) -> Self

Sets the journal compaction threshold.

Once the journal has grown by more than bytes since the last compaction, the event loop compacts it after the next successful flush. A value around 1 MiB (1 048 576) suits most workloads. Without it the journal is never compacted automatically.

pub(crate) async fn build(self) -> Result<(JournaledSession, FileStore)>

Replays the journal and opens it for appending.

Trait Implementations

impl From<FilePersistence> for SessionPersistence

fn from(config: FilePersistence) -> Self

Converts to this type from the input type.
