Struct Transaction 

pub struct Transaction {
    pub version: i32,
    pub inputs: Vec<TxIn>,
    pub outputs: Vec<TxOut>,
    pub witnesses: Vec<Vec<Vec<u8>>>,
    pub locktime: u32,
}

A Bitcoin transaction with optional witness data.

Fields

version: i32

Transaction version (typically 1 or 2).

inputs: Vec<TxIn>

Transaction inputs.

outputs: Vec<TxOut>

Transaction outputs.

witnesses: Vec<Vec<Vec<u8>>>

Per-input witness stacks (empty for legacy transactions).

locktime: u32

Lock time.

Implementations

impl Transaction

pub fn new(version: i32) -> Self

Create a new empty transaction.

pub fn has_witness(&self) -> bool

Returns true if any input has witness data.

pub fn serialize_legacy(&self) -> Vec<u8>

Serialize without witness data (used for txid computation).

pub fn serialize_witness(&self) -> Vec<u8>

Serialize with witness data (BIP-144 format).

If no witnesses exist, falls back to legacy serialization.

pub fn txid(&self) -> [u8; 32]

Compute the transaction ID (double-SHA256 of legacy serialization, reversed).

The txid is displayed in reversed byte order by convention.

pub fn wtxid(&self) -> [u8; 32]

Compute the witness transaction ID (wtxid).

For legacy transactions, wtxid == txid.

pub fn vsize(&self) -> usize

Compute the virtual size (vsize) for fee calculation.

vsize = ceil((weight + 3) / 4) where weight = base_size * 3 + total_size

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.
