Struct pallet_grandpa::EquivocationHandler

pub struct EquivocationHandler<I, R, L, O = GrandpaEquivocationOffence<I>> { /* fields omitted */ }

Generic equivocation handler. This type implements HandleEquivocation using existing subsystems that are part of frame (type bounds described below) and will dispatch to them directly, it’s only purpose is to wire all subsystems together.

Trait Implementations

impl<I, R, L, O> Default for EquivocationHandler<I, R, L, O>

fn default() -> Self

Returns the “default value” for a type.

impl<T, R, L, O> HandleEquivocation<T> for EquivocationHandler<T::KeyOwnerIdentification, R, L, O> where
    T: Config + Config + SendTransactionTypes<Call<T>>,
    R: ReportOffence<T::AccountId, T::KeyOwnerIdentification, O>,
    L: Get<u64>,
    O: GrandpaOffence<T::KeyOwnerIdentification>, 

type Offence = O

The offence type used for reporting offences on valid equivocation reports.

type ReportLongevity = L

The longevity, in blocks, that the equivocation report is valid for. When using the staking pallet this should be equal to the bonding duration (in blocks, not eras).

fn report_offence(
    reporters: Vec<T::AccountId>,
    offence: O
) -> Result<(), OffenceError>

Report an offence proved by the given reporters.

fn is_known_offence(
    offenders: &[T::KeyOwnerIdentification],
    time_slot: &O::TimeSlot
) -> bool

Returns true if all of the offenders at the given time slot have already been reported.

fn submit_unsigned_equivocation_report(
    equivocation_proof: EquivocationProof<T::Hash, T::BlockNumber>,
    key_owner_proof: T::KeyOwnerProof
) -> DispatchResult

Create and dispatch an equivocation report extrinsic.

fn block_author() -> Option<T::AccountId>

Fetch the current block author id, if defined.
