Trait Broadcaster

pub trait Broadcaster<Cfg: Config>:
    Clone
    + Send
    + 'static {
    type Message: Codec<Cfg> + Clone + Send + 'static;
    type Response: Clone + Send + 'static;

    // Required method
    fn broadcast(
        &mut self,
        message: Self::Message,
    ) -> impl Future<Output = Receiver<Self::Response>> + Send;
}

Broadcaster is the interface responsible for attempting replication of messages across a network.

Required Associated Types

type Message: Codec<Cfg> + Clone + Send + 'static

Message is the type of data that can be broadcasted.

It must implement the Codec trait so that it can be:

• serialized upon broadcast
• deserialized upon reception

type Response: Clone + Send + 'static

Response is the type of data that is returned once the message is broadcasted.

It may also indicate the success or failure of the broadcast attempt.

Required Methods

fn broadcast( &mut self, message: Self::Message, ) -> impl Future<Output = Receiver<Self::Response>> + Send

Attempt to broadcast a message to the network.

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.
