In-memory block store stub

Implementations

impl MemoryBlockStore

pub fn new() -> Self

pub fn new_shared() -> SharedBlockStore

Create a new in-memory block store wrapped in Arc<parking_lot::RwLock<Box<dyn BlockStore>>>, ready for use with ConsensusEngine.

Trait Implementations

impl BlockStore for MemoryBlockStore

fn put_block(&mut self, block: Block)

fn get_block(&self, hash: &BlockHash) -> Option<Block>

fn get_block_by_height(&self, h: Height) -> Option<Block>

fn get_blocks_in_range(&self, from: Height, to: Height) -> Vec<Block>

Get blocks in [from, to] inclusive. Default iterates one-by-one.

fn tip_height(&self) -> Height

Return the highest stored block height.

fn put_commit_qc(&mut self, height: Height, qc: QuorumCertificate)

Store the QC that committed a block at the given height.

fn get_commit_qc(&self, height: Height) -> Option<QuorumCertificate>

Retrieve the commit QC for a block at the given height.

fn flush(&self)

Flush pending writes to durable storage.

fn put_tx_index(&mut self, _tx_hash: [u8; 32], _height: Height, _index: u32)

Store a tx hash → (height, index) mapping.

fn get_tx_location(&self, _tx_hash: &[u8; 32]) -> Option<(Height, u32)>

Look up a tx hash → (height, index_in_block).

fn put_block_results(&mut self, _height: Height, _results: EndBlockResponse)

Store the EndBlockResponse for a given height.

fn get_block_results(&self, _height: Height) -> Option<EndBlockResponse>

Retrieve the EndBlockResponse for a given height.

impl Default for MemoryBlockStore

fn default() -> Self

Returns the “default value” for a type.
