BlockWriteSender

zebra_state::service::write

Struct BlockWriteSender 

Source 
pub(super) struct BlockWriteSender {
    pub non_finalized: Option<UnboundedSender<NonFinalizedWriteMessage>>,
    pub finalized: Option<UnboundedSender<(CheckpointVerifiedBlock, Sender<Result<Hash, CommitCheckpointVerifiedError>>)>>,
}
Expand description

A worker with a task that reads, validates, and writes blocks to the finalized_state or non_finalized_state and channels for sending it blocks.

Fields§

§non_finalized: Option<UnboundedSender<NonFinalizedWriteMessage>>

A channel to send blocks to the block_write_task, so they can be written to the NonFinalizedState.

§finalized: Option<UnboundedSender<(CheckpointVerifiedBlock, Sender<Result<Hash, CommitCheckpointVerifiedError>>)>>

A channel to send blocks to the block_write_task, so they can be written to the FinalizedState.

This sender is dropped after the state has finished sending all the checkpointed blocks, and the lowest semantically verified block arrives.
