Struct breez_sdk_core::bitcoin::blockdata::transaction::TxIn

pub struct TxIn {
    pub previous_output: OutPoint,
    pub script_sig: Script,
    pub sequence: Sequence,
    pub witness: Witness,
}

Bitcoin transaction input.

It contains the location of the previous transaction’s output, that it spends and set of scripts that satisfy its spending conditions.

Fields

previous_output: OutPoint

The reference to the previous output that is being used an an input.

script_sig: Script

The script which pushes values on the stack which will cause the referenced output’s script to be accepted.

sequence: Sequence

The sequence number, which suggests to miners which of two conflicting transactions should be preferred, or 0xFFFFFFFF to ignore this feature. This is generally never used since the miner behaviour cannot be enforced.

witness: Witness

Witness data: an array of byte-arrays. Note that this field is not (de)serialized with the rest of the TxIn in Encodable/Decodable, as it is (de)serialized at the end of the full Transaction. It is (de)serialized with the rest of the TxIn in other (de)serialization routines.

Implementations

impl TxIn

pub fn enables_lock_time(&self) -> bool

Returns true if this input enables the LockTime (aka nLockTime) of its Transaction.

nLockTime is enabled if any input enables it. See Transaction::is_lock_time_enabled to check the overall state. If none of the inputs enables it, the lock time value is simply ignored. If this returns false and OP_CHECKLOCKTIMEVERIFY is used in the redeem script with this input then the script execution will fail [BIP-0065].

Trait Implementations

impl Clone for TxIn

fn clone(&self) -> TxIn

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxIn

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

Formats the value using the given formatter.

impl Decodable for TxIn

fn consensus_decode_from_finite_reader<R>(r: &mut R) -> Result<TxIn, Error>

where R: Read + ?Sized,

Decode Self from a size-limited reader.

fn consensus_decode<R>(reader: &mut R) -> Result<Self, Error>

where R: Read + ?Sized,

Decode an object with a well-defined format.

impl Default for TxIn

fn default() -> TxIn

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TxIn

fn deserialize<__D>( __deserializer: __D, ) -> Result<TxIn, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encodable for TxIn

fn consensus_encode<W>(&self, w: &mut W) -> Result<usize, Error>

where W: Write + ?Sized,

Encode an object with a well-defined format. Returns the number of bytes written on success.

impl Hash for TxIn

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TxIn

fn cmp(&self, other: &TxIn) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TxIn

fn eq(&self, other: &TxIn) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TxIn

fn partial_cmp(&self, other: &TxIn) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TxIn

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
