Struct noble_grandpa::EquivocationHandler

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

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

Trait Implementations
