Trait Implementations

impl ChainStatus<Block<Header<u32, BlakeTwo256>, OpaqueExtrinsic>, Justification> for SubstrateChainStatus

type Error = Error

fn finalized_at( &self, number: BlockNumber ) -> Result<FinalizationStatus<Justification>, 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.

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

Export a copy of the block.

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

The status of the block.

fn best_block(&self) -> Result<PhronHeader, Self::Error>

The header of the best block.

fn top_finalized(&self) -> Result<Justification, Self::Error>

The justification of the top finalized block.

fn children(&self, id: BlockId) -> Result<Vec<PhronHeader>, Self::Error>

Children of the specified block.

impl Clone for SubstrateChainStatus

fn clone(&self) -> SubstrateChainStatus

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
