    fn can_propagate<N>(&self, peer: &mut PeerMetadata<N>) -> bool

    fn on_session_closed<N>(&mut self, peer: &mut PeerMetadata<N>)
       where N: NetworkPrimitives;
}

A policy defining which peers pending transactions are gossiped to.

Required Methods

fn can_propagate<N>(&self, peer: &mut PeerMetadata<N>) -> bool

where N: NetworkPrimitives,

Filter a given peer based on the policy.

This determines whether transactions can be propagated to this peer.

fn on_session_established<N>(&mut self, peer: &mut PeerMetadata<N>)

where N: NetworkPrimitives,

A callback on the policy when a new peer session is established.

fn on_session_closed<N>(&mut self, peer: &mut PeerMetadata<N>)

where N: NetworkPrimitives,

A callback on the policy when a peer session is closed.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
