LevinMessage

cuprate_levin::message

Enum LevinMessage 

Source 
pub enum LevinMessage<T: LevinBody> {
    Body(T),
    Bucket(Bucket<T::Command>),
    Dummy(usize),
}
Expand description

A levin message that can be sent to a peer.

Variants§

§

Body(T)

A message body.

A levin header will be added to this message before it is sent to the peer.

§

Bucket(Bucket<T::Command>)

A full levin bucket.

This bucket will be sent to the peer directly with no extra information.

This should only be used to send fragmented messages: make_fragmented_messages

§

Dummy(usize)

A dummy message.

A dummy message which the peer will ignore. The dummy message will be the exact size (in bytes) of the given usize on the wire.
