Enum WroteCommit 

pub enum WroteCommit {
    Yes,
    No,
}

Whether WalRecorder::commit actually wrote a TxCommit to the log. Read-only queries — those that never trigger MutationRecorder::record — return WroteCommit::No so the host can skip the surrounding flush() and avoid a per-query fsync just to record an empty transaction.

Variants

Yes

A TxBegin had been lazily allocated and was paired with a matching TxCommit. Caller should flush() (under PerCommit).

No

No mutation events fired during the query, so neither TxBegin nor TxCommit was appended. Caller can skip flush() entirely.

Trait Implementations

impl Clone for WroteCommit

fn clone(&self) -> WroteCommit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WroteCommit

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

Formats the value using the given formatter.

impl PartialEq for WroteCommit

fn eq(&self, other: &WroteCommit) -> 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.
