Required Associated Types

type Batch: SimplifiedBatch + Serialize + DeserializeOwned + Default

The batch type.

Required Associated Constants

const MAX_BATCH_SIZE: usize

The maximal number of items in a batch.

const MAX_BATCH_TOTAL_SIZE: usize

The maximal number of bytes of a batch.

const MAX_VALUE_SIZE: usize

The maximal size of values that can be stored.

Required Methods

fn write_batch<'life0, 'async_trait>( &'life0 self, batch: Self::Batch, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Writes the batch to the database.
