Expand description

A trait for providing blocks of source data for partitions.

Required Methods§

Source

fn is_empty(&self) -> bool

Returns true if there are no blocks in the source.

Source

fn get_nb_blocks(&self) -> i64

Returns the number of blocks in the source.

Source

fn get_max_payload_size(&self) -> i64

Returns the maximum payload size of the blocks in the source.

Source

fn get_source_data_hash(&self) -> Vec<u8> ⓘ

Returns a hash of the source data.

Source

fn get_blocks_stream<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Pin<Box<dyn Stream<Item = Result<Arc<PartitionSourceBlock>, Error>> + Send>>> + Send + 'async_trait>>
where 'life0: 'async_trait, Self: 'async_trait,

Returns a stream of the source blocks.
