Fields

wal_max_frame: u64

max frame in the WAL after checkpoint note, that as we TRUNCATE wal outside of the main checkpoint routine - this field will be set to non-zero number even for TRUNCATE mode

wal_total_backfilled: u64

total amount of frames backfilled to the DB file after checkpoint

wal_checkpoint_backfilled: u64

amount of new frames backfilled to the DB file during this checkpoint procedure

db_truncate_sent: bool

db_sync_sent: bool

wal_truncate_sent: bool

Whether WAL truncation I/O has been submitted (for TRUNCATE checkpoint mode)

wal_sync_sent: bool

Whether WAL sync I/O has been submitted after truncation

Implementations

impl CheckpointResult

pub fn new( wal_max_frame: u64, wal_total_backfilled: u64, wal_checkpoint_backfilled: u64, ) -> Self

pub const fn everything_backfilled(&self) -> bool

pub fn should_truncate(&self) -> bool

pub fn release_guard(&mut self)

Trait Implementations

impl Clone for CheckpointResult

fn clone(&self) -> CheckpointResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointResult

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

Formats the value using the given formatter.

impl Default for CheckpointResult

fn default() -> CheckpointResult

Returns the “default value” for a type.

impl Drop for CheckpointResult

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
