Trait MmrClient

pub trait MmrClient<B, BE>:
    BlockchainEvents<B>
    + HeaderBackend<B>
    + HeaderMetadata<B>
    + ProvideRuntimeApi<B>
where
    B: Block,
    BE: Backend<B>,
    Self::Api: MmrApi<B, MmrRootHash, NumberFor<B>>,
{
    // Provided method
    fn first_mmr_block_num(
        &self,
        notification: &FinalityNotification<B>,
    ) -> Option<NumberFor<B>> { ... }
}

A convenience MMR client trait that defines all the type bounds a MMR client has to satisfy and defines some helper methods.

Provided Methods

fn first_mmr_block_num( &self, notification: &FinalityNotification<B>, ) -> Option<NumberFor<B>>
