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.

Methods

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 pegin_data(&self) -> Option<PeginData>

Extracts witness data from a pegin. Will return None if any data cannot be parsed. The combination of is_pegin() returning true and pegin_data() returning None indicates an invalid transaction.

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 Debug for TxIn

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

Formats the value using the given formatter.

impl Decodable for TxIn

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

Decode an object with a well-defined format

impl Encodable for TxIn

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

Encode an object with a well-defined format, should only ever error if the underlying Write errors. Returns the number of bytes written on success

impl Eq for TxIn

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].

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 ==.
