Computes the voting power in a commit against a validator set.

This trait provides default implementation of some helper functions.

Required methods

pub fn voting_power_in(
    &self,
    signed_header: &SignedHeader,
    validator_set: &ValidatorSet,
    trust_threshold: TrustThreshold
) -> Result<VotingPowerTally, VerificationError>[src]

Compute the voting power in a header and its commit against a validator set.

The trust_threshold is currently not used, but might be in the future for optimization purposes.

Provided methods

pub fn total_power_of(&self, validator_set: &ValidatorSet) -> u64[src]

Compute the total voting power in a validator set

pub fn check_enough_trust(
    &self,
    untrusted_header: &SignedHeader,
    trusted_validators: &ValidatorSet,
    trust_threshold: TrustThreshold
) -> Result<(), VerificationError>[src]

Check against the given threshold that there is enough trust between an untrusted header and a trusted validator set

pub fn check_signers_overlap(
    &self,
    untrusted_header: &SignedHeader,
    untrusted_validators: &ValidatorSet
) -> Result<(), VerificationError>[src]
