Struct pallet_babe::EquivocationHandler[−][src]

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

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.

Trait Implementations

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

[src]

fn default() -> Self

Returns the “default value” for a type. Read more
