Struct pallet_grandpa::EquivocationHandler
source · [−]pub struct EquivocationHandler<I, R, L, O = GrandpaEquivocationOffence<I>> { /* private fields */ }Expand description
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.

type Offence = O
type Offence = O
The offence type used for reporting offences on valid equivocation reports.
type ReportLongevity = L
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). Read more
