Implementations

impl Blockchain

pub fn new(network: Network) -> Blockchain

Constructs a new blockchain

pub fn get_block(&self, hash: Sha256dHash) -> Option<&BlockchainNode>

Looks up a block in the chain and returns the BlockchainNode containing it

pub fn add_txdata(&mut self, block: Block) -> Result<(), BlockchainError>

Locates a block in the chain and overwrites its txdata

pub fn remove_txdata( &mut self, hash: Sha256dHash, ) -> Result<(), BlockchainError>

Locates a block in the chain and removes its txdata

pub fn add_header(&mut self, header: BlockHeader) -> Result<(), BlockchainError>

Adds a block header to the chain

pub fn add_block(&mut self, block: Block) -> Result<(), BlockchainError>

Adds a block to the chain

pub fn genesis_hash(&self) -> Sha256dHash

Returns the genesis block’s blockhash

pub fn best_tip(&self) -> &Block

Returns the best tip

pub fn best_tip_height(&self) -> u32

Returns the best tip height

pub fn best_tip_hash(&self) -> Sha256dHash

Returns the best tip’s blockhash

pub fn locator_hashes(&self) -> Vec<Sha256dHash>

Returns an array of locator hashes used in getheaders messages

pub fn iter(&self, start_hash: Sha256dHash) -> BlockIter<'_>

An iterator over all blocks in the chain starting from start_hash

pub fn rev_iter(&self, start_hash: Sha256dHash) -> RevBlockIter<'_>

An iterator over all blocks in reverse order to the genesis, starting with start_hash

pub fn rev_stale_iter(&self, start_hash: Sha256dHash) -> RevStaleBlockIter<'_>

An iterator over all blocks -not- in the best chain, in reverse order, starting from start_hash

Trait Implementations

impl<D: Decoder> Decodable<D> for Blockchain

fn consensus_decode(d: &mut D) -> Result<Blockchain, Error>

Decode an object with a well-defined format

impl<S: Encoder> Encodable<S> for Blockchain

fn consensus_encode(&self, s: &mut S) -> Result<(), Error>

Encode an object with a well-defined format, should only ever error if the underlying Encoder errors.
