Struct mz_persist::client::DecodedSnapshot

source · [−]

pub struct DecodedSnapshot<K, V> { /* private fields */ }

Expand description

A consistent snapshot of all data currently stored for an id, with keys and vals decoded.

Implementations

source

impl<K: Codec, V: Codec> DecodedSnapshot<K, V>

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.

source

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

A logical upper bound on the times that had been added to the collection when this snapshot was taken

source

pub fn into_iters(
 self,
 num_iters: NonZeroUsize
) -> Vec<DecodedSnapshotIter<K, V>>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

Returns a set of num_iters Iterators that each output roughly 1/num_iters of the data represented by this snapshot.

source

pub fn into_iter(self) -> DecodedSnapshotIter<K, V>ⓘNotable traits for DecodedSnapshotIter<K, V>`impl<K: Codec, V: Codec> Iterator for DecodedSnapshotIter<K, V> type Item = Result<((K, V), u64, i64), Error>;`

Returns a single Iterator that outputs the data represented by this snapshot.
