Required Methods§

source

fn status_of(&self, id: BlockId) -> Result<BlockStatus<J>, Self::Error>

The status of the block.

source

fn block(&self, id: BlockId) -> Result<Option<B>, Self::Error>

Export a copy of the block.

source

fn finalized_at( &self, number: u32 ) -> Result<FinalizationStatus<J>, Self::Error>

The justification at this block number, if we have it otherwise just block id if the block is finalized without justification. Should return NotFinalized variant if the request is above the top finalized.
