Trait sp_staking::offence::OnOffenceHandler

pub trait OnOffenceHandler<Reporter, Offender> {
    fn on_offence(
        offenders: &[OffenceDetails<Reporter, Offender>], 
        slash_fraction: &[Perbill], 
        session: SessionIndex
    );
}

A trait to take action on an offence.

Used to decouple the module that handles offences and the one that should punish for those offences.

Required methods

fn on_offence(
    offenders: &[OffenceDetails<Reporter, Offender>],
    slash_fraction: &[Perbill],
    session: SessionIndex
)

A handler for an offence of a particular kind.

Note that this contains a list of all previous offenders as well. The implementer should cater for a case, where the same authorities were reported for the same offence in the past (see OffenceCount).

The vector of slash_fraction contains Perbills the authorities should be slashed and is computed according to the OffenceCount already. This is of the same length as offenders. Zero is a valid value for a fraction.

The session parameter is the session index of the offence.
