Expand description

Provides Batches for the BatchQueue and BatchValidator stages.

Required Methods§

Source

fn next_batch<'life0, 'life1, 'async_trait>( &'life0 mut self, parent: L2BlockInfo, l1_origins: &'life1 [BlockInfo], ) -> Pin<Box<dyn Future<Output = Result<Batch, PipelineErrorKind>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Returns the next Batch in the ChannelReader stage, if the stage is not complete. This function can only be called once while the stage is in progress, and will return None on subsequent calls unless the stage is reset or complete. If the stage is complete and the batch has been consumed, an PipelineError::Eof error is returned.

Source

fn span_buffer_size(&self) -> usize

Returns the number of SingleBatches that are currently buffered in the BatchStream from a SpanBatch.

Source

fn flush(&mut self)

Allows the stage to flush the buffer in the crate::stages::BatchStream if an invalid single batch is found. Pre-holocene hardfork, this will be a no-op.
