Struct PruneQuery 

pub struct PruneQuery {
    pub status: EffectStatus,
    pub older_than: Duration,
    pub now: SystemTime,
    pub limit: usize,
}

Which records EffectStore::prune deletes: those in a settled status that last changed at least older_than before now and hold no live lease at now.

The age is a duration, not a cutoff time, so a store that reads its own clock (like PostgreSQL’s) can apply it to that clock.

Fields

status: EffectStatus

The status to prune. Must be settled.

older_than: Duration

The minimum time since the record’s last transition (updated_at).

now: SystemTime

The current time.

limit: usize

At most this many records.

Implementations

impl PruneQuery

pub const DEFAULT_LIMIT: usize = 500

The default batch size.

pub fn new(status: EffectStatus, older_than: Duration, now: SystemTime) -> Self

Records in status settled at least older_than before now.

pub fn limit(self, limit: usize) -> Self

Caps the batch size.

pub fn cutoff(&self) -> Option<SystemTime>

The latest updated_at a record may have to be pruned, or None if that time cannot be represented (nothing is that old).

pub fn matches(&self, record: &EffectRecord) -> bool

Whether record should be pruned (ignoring limit).
