Module state_root_task 

State root task interface types shared between the engine tree and the payload builder. State-root task interface types shared between the engine tree and the payload builder.

The “state-root task” is the background multiproof and sparse-trie pipeline that computes state roots incrementally while a block executes. This module holds its boundary types: the input messages, the StateRootSink and stream views that feed it, and the handles that await its result. The per-block strategy abstraction that decides whether and how the task runs lives in reth-engine-tree under tree::state_root_strategy.

Structs

PayloadStateRootHandle

Opaque state-root task handle passed to payload builders.

StateAccessHint

Hashed account and storage keys that a state-root task may want to prefetch.

StateRootComputeOutcome

Outcome of the state root computation, including the state root itself with the trie updates.

StateRootHandle

Handle to a background sparse trie state root computation.

StateRootHintStream

Hint-only view of a state-root stream.

StateRootTaskCancelGuard

Guard that cancels a state-root task when dropped.

StateRootUpdateHook

EVM hook that forwards state updates into a StateRootSink.

StateRootUpdateStream

Authoritative update capability of a state-root stream.

Enums

StateRootMessage

Messages used internally by the multi proof task.

Traits

StateRootSink

Semantic update stream consumed by state-root tasks.

Functions

evm_state_to_hashed_post_state

Converts [EvmState] to HashedPostState by keccak256-hashing addresses and storage slots.
