Replay

commonware_storage::journal::segmented::oversized

Struct Replay 

Source 
pub struct Replay<E: Context, I: Record, V: Codec> { /* private fields */ }
Expand description

Owned replay reader over an Oversized’s index entries.

Yields (section, position, entry) in order. Dropping the reader before it is exhausted destroys the journal: recovery is re-initialization. Call Replay::finish on an exhausted reader to get the journal back.

Implementations§

Source§

impl<E: Context, I: Record + Send + Sync, V: CodecShared> Replay<E, I, V>

Source

pub async fn next(&mut self) -> Option<Result<(u64, u64, I), Error>>

Returns the next (section, position, entry), or None once every section is exhausted.

An index error ends the section that produced it, and iteration continues with the next section. A value-verification error is returned without ending its section and dooms the tracked replay: finishing it fails with Error::ReplayFailed. Errors while mutating storage to repair a section, and Error::ReplayInterrupted, end the replay.

Source

pub fn finish(self) -> Result<Oversized<E, I, V>, Error>

Returns the journal.

Fails when the reader was not fully drained or yielded an error: the journal is destroyed and recovery is re-initialization.

Source

pub async fn finish_tracked(self) -> Result<Oversized<E, I, V>, Error>

Finish marker-aware startup recovery and return the tracked journal.
