Trait Application

pub trait Application:
    Clone
    + Send
    + 'static {
    type Context;
    type Digest: Array;

    // Required method
    fn verify(
        &mut self,
        context: Self::Context,
        payload: Self::Digest,
    ) -> impl Future<Output = Receiver<bool>> + Send;
}

Application is the interface responsible for processing messages received from the network.

Required Associated Types

type Context

Context is metadata provided by the broadcast engine to associated with a given payload. This could include things like the public key of the sequencer.

type Digest: Array

Digest is an arbitrary hash digest.

Required Methods

fn verify( &mut self, context: Self::Context, payload: Self::Digest, ) -> impl Future<Output = Receiver<bool>> + Send

Verify a proposed payload received from the network.

Returns a future that resolves to a boolean indicating success. Part of verification requires ensuring that the data is made available. For example, by storing it in a database.

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.
