    ) -> Self::CreateProposer;
}

Environment for a Consensus instance.

Creates proposer instance.

Required Associated Types

type Proposer: Proposer<B> + Send + 'static

The proposer type this creates.

type CreateProposer: Future<Output = Result<Self::Proposer, Self::Error>> + Send + Unpin + 'static

A future that resolves to the proposer.

type Error: From<Error> + Error + 'static

Error which can occur upon creation.

Required Methods

fn init(&mut self, parent_header: &<B as Block>::Header) -> Self::CreateProposer

Initialize the proposal logic on top of a specific header. Provide the authorities at that header.
