Struct bitcoin::blockdata::transaction::TxIn

pub struct TxIn {
    pub previous_output: OutPoint,
    pub script_sig: Script,
    pub sequence: u32,
    pub witness: Vec<Vec<u8>>,
}

A transaction input, which defines old coins to be consumed

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 accept

sequence: u32

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: Vec<Vec<u8>>

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.

Trait Implementations

impl Encodable for TxIn

fn consensus_encode<S: Write>(&self, s: S) -> Result<usize, Error>

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

impl Decodable for TxIn

fn consensus_decode<D: Read>(d: D) -> Result<Self, Error>

Decode an object with a well-defined format

impl Default for TxIn

fn default() -> TxIn

Returns the "default value" for a type.

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 PartialEq<TxIn> for TxIn

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for TxIn

impl Debug for TxIn

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

Formats the value using the given formatter.

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, 

Feeds a slice of this type into the given [Hasher].
