Enum CheckpointMode 

pub enum CheckpointMode {
    Noop,
    Passive,
    Full,
    Restart,
    Truncate,
}

SQLite’s checkpoint modes (PRAGMA wal_checkpoint).

Variants

Noop

Copy nothing: only report how many frames the WAL holds, and how many of them are in the database file.

Passive

Copy what no reader still needs, without waiting.

Full

Wait for the writer lock and for readers, then copy the whole WAL.

Restart

As Full, then wait for readers to leave the WAL, so the next commit writes the WAL from its start.

Truncate

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

Trait Implementations

impl Clone for CheckpointMode

fn clone(&self) -> CheckpointMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CheckpointMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for CheckpointMode

fn eq(&self, other: &CheckpointMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
