Struct SigningContext 

pub struct SigningContext<'a> {
    pub raw_tx: &'a [u8],
    pub input_index: usize,
    pub source_satoshis: u64,
    pub locking_script: &'a Script,
}

Context for signing a transaction input.

This provides all the information needed to compute a sighash and produce a signature for a specific input.

Fields

raw_tx: &'a [u8]

The raw transaction bytes being signed.

input_index: usize

The index of the input being signed.

source_satoshis: u64

The satoshi value of the UTXO being spent.

locking_script: &'a Script

The locking script of the UTXO being spent.

Implementations

impl<'a> SigningContext<'a>

pub fn new( raw_tx: &'a [u8], input_index: usize, source_satoshis: u64, locking_script: &'a Script, ) -> Self

Creates a new signing context.

pub fn compute_sighash(&self, scope: u32) -> Result<[u8; 32]>

Computes the sighash for this input with the given scope.

The scope should include SIGHASH_FORKID for BSV transactions.

Trait Implementations

impl<'a> Clone for SigningContext<'a>

fn clone(&self) -> SigningContext<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SigningContext<'a>

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

Formats the value using the given formatter.
