Implementations§

source§

impl<K, V, T, D> BatchBuilder<K, V, T, D>
where K: Debug + Codec, V: Debug + Codec, T: Timestamp + Lattice + Codec64, D: Semigroup + Codec64,

source

pub async fn finish( self, registered_upper: Antichain<T>, ) -> Result<Batch<K, V, T, D>, InvalidUsage<T>>

Finish writing this batch and return a handle to the written batch.

This fails if any of the updates in this batch are beyond the given upper.

source

pub async fn add( &mut self, key: &K, val: &V, ts: &T, diff: &D, ) -> Result<Added, InvalidUsage<T>>

Adds the given update to the batch.

The update timestamp must be greater or equal to lower that was given when creating this BatchBuilder.
