Trait ethcore::engines::epoch::EpochVerifier[−][src]

pub trait EpochVerifier<M: Machine>: Send + Sync {
    fn verify_light(&self, header: &M::Header) -> Result<(), M::Error>;

    fn verify_heavy(&self, header: &M::Header) -> Result<(), M::Error> { ... }
    fn check_finality_proof(&self, _proof: &[u8]) -> Option<Vec<H256>> { ... }
}

Verifier for all blocks within an epoch with self-contained state.

Required Methods

`fn verify_light(&self, header: &M::Header) -> Result<(), M::Error>`

Lightly verify the next block header. This may not be a header belonging to a different epoch.

Provided Methods

`fn verify_heavy(&self, header: &M::Header) -> Result<(), M::Error>`

Perform potentially heavier checks on the next block header.

`fn check_finality_proof(&self, _proof: &[u8]) -> Option<Vec<H256>>`

Check a finality proof against this epoch verifier. Returns Some(hashes) if the proof proves finality of these hashes. Returns None if the proof doesn't prove anything.
