Trait Implementations

impl Cache for UnboundedCache

fn look_up(&self, block_hash: &BlockHash) -> Option<&ValidatedBlockHeader>

Retrieves the block header keyed by the given block hash.

fn block_connected( &mut self, block_hash: BlockHash, block_header: ValidatedBlockHeader )

Called when a block has been connected to the best chain to ensure it is available to be disconnected later if needed.

fn block_disconnected( &mut self, block_hash: &BlockHash ) -> Option<ValidatedBlockHeader>

Called when a block has been disconnected from the best chain. Once disconnected, a block’s header is no longer needed and thus can be removed.
