Struct elements::TxIn

pub struct TxIn {
    pub previous_output: OutPoint,
    pub is_pegin: bool,
    pub has_issuance: bool,
    pub script_sig: Script,
    pub sequence: u32,
    pub asset_issuance: AssetIssuance,
    pub witness: TxInWitness,
}

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

is_pegin: bool

Flag indicating that previous_outpoint refers to something on the main chain

has_issuance: bool

Flag indicating that previous_outpoint has an asset issuance attached

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.

asset_issuance: AssetIssuance

Asset issuance data

witness: TxInWitness

Witness data - not deserialized/serialized as part of a TxIn object (rather as part of its containing transaction, if any) but is logically part of the txin.

Implementations

impl TxIn

pub fn is_coinbase(&self) -> bool

Whether the input is a coinbase

pub fn is_pegin(&self) -> bool

Whether the input is a pegin

pub fn has_issuance(&self) -> bool

Helper to determine whether an input has an asset issuance attached

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<D: SimpleDecoder> ConsensusDecodable<D> for TxIn

fn consensus_decode(d: &mut D) -> Result<TxIn, Error>

Decode an object with a well-defined format

impl<S: SimpleEncoder> ConsensusEncodable<S> for TxIn

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

Encode an object with a well-defined format

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,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

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: &Rhs) -> bool

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