Struct SnapshotStaging 

pub struct SnapshotStaging { /* private fields */ }

One snapshot’s staging, from its first batch to the load or file check that reads its records, or the discard that removes them (§16.2). It is the one holder of what it stages for that whole operation: its steps are its phases, and the load takes it whole. Dropped while still holding records, as by a cancelled or panicking caller, it removes them.

Implementations

impl SnapshotStaging

pub async fn digest(&self) -> Result<StagedDigest, DbError>

The digest of the records it holds now (§19.1).

impl SnapshotStaging

pub async fn stage(&mut self, plaintext: Vec<u8>) -> Result<(), DbError>

Decode one batch of opened plaintext and commit its records together. After a failure, discard this staging.

pub async fn finish(&mut self) -> Result<(), DbError>

Refuse a stream without its header, declared records and end marker, then check its applied writes. Nothing more stages after this; after a failure, discard this staging.

pub async fn discard(self) -> Result<(), DbError>

Remove everything staged so far (§16.2).

Trait Implementations

impl Drop for SnapshotStaging

fn drop(&mut self)
