}

The bitcoin block and additional metadata returned by the iterate method

Fields

block: Block

The bitcoin block

block_hash: BlockHash

The bitcoin block hash, same as block.block_hash() but result from hashing is cached

size: u32

The byte size of the block, as returned by in serialize(block).len()

next: Vec<BlockHash>

Hash of the blocks following this one, it’s a vec because during reordering they may be more than one because of reorgs, as a result from iterate, it’s just one.

height: u32

The height of the current block, number of blocks between this one and the genesis block

outpoint_values: HashMap<OutPoint, TxOut>

All the previous outputs of this block. Allowing to validate the script or computing the fee Note that when configuration skip_script_pubkey is true, the script is empty, when skip_prevout is true, this map is empty.

tx_hashes: HashSet<Txid>

Precomputed set of txid present in block

Implementations

impl BlockExtra

pub fn average_fee(&self) -> Option<f64>

Returns the average transaction fee in the block

pub fn fee(&self) -> Option<u64>

Returns the total fee of the block

pub fn tx_fee(&self, tx: &Transaction) -> Option<u64>

Returns the fee of a transaction contained in the block

Trait Implementations

impl Debug for BlockExtra

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
