Expand description
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
Implementations
sourceimpl Transaction
impl Transaction
sourcepub fn ntxid(&self) -> Sha256dHash
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.
sourcepub fn txid(&self) -> Sha256dHash
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.
sourcepub fn signature_hash(
&self,
input_index: usize,
script_pubkey: &Script,
sighash_u32: u32
) -> Sha256dHash
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()
sourcepub fn get_weight(&self) -> u64
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.
sourcepub fn is_coin_base(&self) -> bool
pub fn is_coin_base(&self) -> bool
Is this a coin base transaction?
