StateRootUpdateStream

reth_trie_parallel::state_root_task

Struct StateRootUpdateStream 

Source 
pub struct StateRootUpdateStream { /* private fields */ }
Expand description

Authoritative update capability of a state-root stream.

A StateRootHandle provides this capability exactly once, so its producer can end the update stream either through the EVM state hook made with Self::into_state_hook (finishes on drop) or through a pre-hashed update stream (calls Self::finish). The type is deliberately not Clone and finishing consumes it, so a second end-of-stream signal cannot be produced.

Dropping the stream without calling Self::finish (for example when a producer dies) deliberately does not finish it: an unfinished stream means the updates are incomplete, and the task must not compute a root from them.

Implementations§

Source§

impl StateRootUpdateStream

Source

pub fn on_hashed_state_update(&self, state: HashedPostState)

Emits an authoritative pre-hashed state update.

Source

pub fn finish(self)

Finishes the authoritative update stream.

Source

pub fn into_state_hook(self) -> StateRootUpdateHook

Converts this capability into an EVM state hook that finishes the stream on drop.

See StateRootUpdateHook for why the hook finishes on drop while the bare stream does not, and how a panic during execution is excluded from that.
