Struct BuildTask

pub struct BuildTask {
    pub engine: Arc<EngineClient>,
    pub cfg: Arc<RollupConfig>,
    pub attributes: OpAttributesWithParent,
    pub is_attributes_derived: bool,
    pub payload_tx: Option<Sender<OpExecutionPayloadEnvelope>>,
}

The BuildTask is responsible for building new blocks and importing them via the engine API.

Fields

engine: Arc<EngineClient>

The engine API client.

cfg: Arc<RollupConfig>

The RollupConfig.

attributes: OpAttributesWithParent

The OpAttributesWithParent to instruct the execution layer to build.

is_attributes_derived: bool

Whether or not the payload was derived, or created by the sequencer.

payload_tx: Option<Sender<OpExecutionPayloadEnvelope>>

An optional channel to send the built OpExecutionPayloadEnvelope to, after the block has been built, imported, and canonicalized.

Implementations

impl BuildTask

pub const fn new( engine: Arc<EngineClient>, cfg: Arc<RollupConfig>, attributes: OpAttributesWithParent, is_attributes_derived: bool, payload_tx: Option<Sender<OpExecutionPayloadEnvelope>>, ) -> Self

Creates a new block building task.

Trait Implementations
