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
