Struct WalCheckpointOutcome 

#[non_exhaustive]
pub struct WalCheckpointOutcome {
    pub busy: bool,
    pub log_frames: Option<i64>,
    pub checkpointed_frames: Option<i64>,
}

Available on crate feature __sqlite-shared only.

The result of a wal_checkpoint run.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

busy: bool

Whether a busy reader or writer stopped the checkpoint early. Only the blocking modes set it: Passive reports false even when it left frames behind.

log_frames: Option<i64>

Frames in the WAL after the checkpoint, None when the database is not in WAL mode.

checkpointed_frames: Option<i64>

Frames of the WAL moved into the database file, None when the database is not in WAL mode. Counted within the current log, so a Truncate run reports Some(0) because the log was emptied, not because nothing was moved.
