Struct FlashBlockService 

Source 
pub struct FlashBlockService<N: NodePrimitives, S, EvmConfig: ConfigureEvm<Primitives = N, NextBlockEnvCtx: From<OpFlashblockPayloadBase> + Unpin>, Provider> { /* private fields */ }
Expand description

Implementations§

Source§

impl<N, S, EvmConfig, Provider> FlashBlockService<N, S, EvmConfig, Provider>
where N: NodePrimitives, S: Stream<Item = Result<FlashBlock>> + Unpin + 'static, EvmConfig: ConfigureEvm<Primitives = N, NextBlockEnvCtx: From<OpFlashblockPayloadBase> + Unpin> + Clone + 'static, Provider: StateProviderFactory + BlockReaderIdExt<Header = HeaderTy<N>, Block = BlockTy<N>, Transaction = N::SignedTx, Receipt = ReceiptTy<N>> + Unpin + Clone + 'static,

Source

pub fn new( incoming_flashblock_rx: S, evm_config: EvmConfig, provider: Provider, spawner: TaskExecutor, compute_state_root: bool, ) -> Self

Constructs a new FlashBlockService that receives FlashBlocks from rx stream.

Source

pub const fn flashblocks_broadcaster(&self) -> &Sender<Arc<FlashBlock>>

Returns the sender half to the received flashblocks.

Source

pub const fn block_sequence_broadcaster( &self, ) -> &Sender<FlashBlockCompleteSequence>

Returns the sender half to the flashblock sequence.

Source

pub fn subscribe_block_sequence(&self) -> FlashBlockCompleteSequenceRx

Returns a subscriber to the flashblock sequence.

Source

pub fn subscribe_in_progress(&self) -> InProgressFlashBlockRx

Returns a receiver that signals when a flashblock is being built.

Source

pub async fn run(self, tx: Sender<Option<PendingFlashBlock<N>>>)

Drives the service and sends new blocks to the receiver.

This loop:

  1. Checks if any build job has completed and processes results
  2. Receives and batches all immediately available flashblocks
  3. Attempts to build a block from the complete sequence

Note: this should be spawned
