PreparedStateRootJob

reth_engine_tree::tree::state_root_strategy

Struct PreparedStateRootJob 

Source 
pub struct PreparedStateRootJob<N: NodePrimitives> { /* private fields */ }
Expand description

Prepared per-block state-root work and its update-stream capabilities.

The capabilities are populated by the strategy’s prepare according to the execution mode: the execution hook on the serial path, the hashed update stream on the parallel BAL path, never both. Each capability is taken once by the code that produces its messages and is not retained here, so the task’s update channel closes when the producers are done.

Implementations§

Source§

impl<N: NodePrimitives> PreparedStateRootJob<N>

Source

pub const fn new( job: Box<dyn StateRootJob<N>>, hashed_state_rx: Option<Receiver<HashedPostState>>, ) -> Self

Creates a prepared state-root job without update-stream capabilities.

Source

pub fn with_execution_hook(self, hook: StateRootUpdateHook) -> Self

Attaches the execution hook capability (serial execution path).

Source

pub fn with_hint_stream(self, hint_stream: StateRootHintStream) -> Self

Attaches the hint stream capability.

Source

pub fn with_hashed_update_stream(self, stream: StateRootUpdateStream) -> Self

Attaches the hashed update stream capability (parallel BAL path).

Source

pub fn name(&self) -> &'static str

Returns the job name used in logs.

Source

pub fn take_execution_hook(&mut self) -> Option<Box<dyn OnStateHook + 'static>>

Takes the execution hook, present only when the job wants normal execution updates.

Source

pub const fn take_hint_stream(&mut self) -> Option<StateRootHintStream>

Takes the hint stream for transaction prewarming.

Source

pub const fn take_hashed_update_stream( &mut self, ) -> Option<StateRootUpdateStream>

Takes the hashed update stream, present only on the parallel BAL path.

Source

pub const fn take_hashed_state_rx( &mut self, ) -> Option<Receiver<HashedPostState>>

Takes the optional hashed-state receiver produced by the job.

The sender behind a returned receiver must either deliver one value or be dropped; validation blocks on it while hashing the post state, so a job that keeps the sender alive without sending stalls block validation.

Source

pub fn finish( &mut self, block: &RecoveredBlock<N::Block>, output: Arc<BlockExecutionOutput<N::Receipt>>, hashed_state: &LazyHashedPostState, ) -> ProviderResult<StateRootJobOutcome>

Completes the job after execution.
