Struct bitcoin::blockdata::transaction::Transaction

pub struct Transaction {
    pub version: u32,
    pub lock_time: u32,
    pub input: Vec<TxIn>,
    pub output: Vec<TxOut>,
}

A Bitcoin transaction, which describes an authenticated movement of coins

Fields

version: u32

The protocol version, should always be 1.

lock_time: u32

Block number before which this transaction is valid, or 0 for valid immediately.

input: Vec<TxIn>

List of inputs

output: Vec<TxOut>

List of outputs

Methods

impl Transaction

pub fn ntxid(&self) -> Sha256dHash

Computes a "normalized TXID" which does not include any signatures. This gives a way to identify a transaction that is ``the same'' as another in the sense of having same inputs and outputs.

pub fn txid(&self) -> Sha256dHash

Computes the txid. For non-segwit transactions this will be identical to the output of BitcoinHash::bitcoin_hash(), but for segwit transactions, this will give the correct txid (not including witnesses) while bitcoin_hash will also hash witnesses.

pub fn signature_hash(     &self,     input_index: usize,     script_pubkey: &Script,     sighash_u32: u32 ) -> Sha256dHash

Computes a signature hash for a given input index with a given sighash flag. To actually produce a scriptSig, this hash needs to be run through an ECDSA signer, the SigHashType appended to the resulting sig, and a script written around this, but this is the general (and hard) part.

Warning This does NOT attempt to support OP_CODESEPARATOR. In general this would require evaluating script_pubkey to determine which separators get evaluated and which don't, which we don't have the information to determine.

Panics

Panics if input_index is greater than or equal to self.input.len()

pub fn get_weight(&self) -> u64

Gets the "weight" of this transaction, as defined by BIP141. For transactions with an empty witness, this is simply the consensus-serialized size times 4. For transactions with a witness, this is the non-witness consensus-serialized size multiplied by 3 plus the with-witness consensus-serialized size.

pub fn is_coin_base(&self) -> bool

Is this a coin base transaction?
