Struct TxIn 

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

Available on crate feature alloc only.

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 as an input.

script_sig: ScriptBuf

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 behavior 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 const EMPTY_COINBASE: TxIn

An empty transaction input with the previous output as for a coinbase transaction.

Trait Implementations

impl<'a> Arbitrary<'a> for TxIn

Available on crate feature arbitrary only.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for TxIn

fn clone(&self) -> TxIn

Returns a duplicate 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

Formats the value using the given formatter.

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

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TxIn

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

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,

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
