Struct ethcore::block::LockedBlock

source · [−]

pub struct LockedBlock { /* private fields */ }

Expand description

Just like ClosedBlock except that we can’t reopen it and it’s faster.

We actually store the post-Engine::on_close_block state, unlike in ClosedBlock where it’s the pre.

Implementations

impl LockedBlock

pub fn strip_receipts_outcomes(&mut self)

Removes outcomes from receipts and updates the receipt root.

This is done after the block is enacted for historical reasons. We allow inconsistency in receipts for some chains if validate_receipts_transition is set to non-zero value, so the check only happens if we detect unmatching root first and then fall back to striped receipts.

pub fn seal(
    self,
    engine: &dyn EthEngine,
    seal: Vec<Bytes>
) -> Result<SealedBlock, Error>

Provide a valid seal in order to turn this into a SealedBlock.

NOTE: This does not check the validity of seal with the engine.

pub fn try_seal(
    self,
    engine: &dyn EthEngine,
    seal: Vec<Bytes>
) -> Result<SealedBlock, Error>

Provide a valid seal in order to turn this into a SealedBlock. This does check the validity of seal with the engine. Returns the ClosedBlock back again if the seal is no good. TODO(https://github.com/openethereum/openethereum/issues/10407): This is currently only used in POW chain call paths, we should really merge it with seal() above.

Methods from Deref<Target = ExecutedBlock>

pub fn env_info(&self) -> EnvInfo
