Struct mz_persist::indexed::snapshot::ArrangementSnapshot

source · [−]

pub struct ArrangementSnapshot(_, _, _, _);

Expand description

A consistent snapshot of all data currently stored for an id.

Implementations

source

impl ArrangementSnapshot

source

pub fn seqno(&self) -> SeqNo

Returns the SeqNo at which this snapshot was run.

All writes assigned a seqno < this are included.

source

pub fn since(&self) -> Antichain<u64>

Returns the since frontier of this snapshot.

All updates at times less than this frontier must be forwarded to some time in this frontier.
