Enum WalCheckpointMode 

#[non_exhaustive]
pub enum WalCheckpointMode {
    Passive,
    Full,
    Restart,
    Truncate,
    Noop,
}

Available on crate feature __sqlite-shared only.

The mode of a wal_checkpoint run, matching the modes of sqlite3_wal_checkpoint_v2.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Passive

Checkpoint what is possible without waiting on readers or writers.

Full

Wait until there is no writer and every reader reads from the most recent snapshot, then checkpoint every frame.

Restart

Like Full, then wait until no reader uses the WAL, so the next writer restarts the log.

Truncate

Like Restart, then truncate the WAL file to zero bytes.

Noop

Report the WAL state without checkpointing anything.

Requires SQLite 3.51.0 or later. Older versions do not know this mode and silently run a Passive checkpoint instead.
