Trait TransactionInputContext 

pub trait TransactionInputContext {
    // Required methods
    fn source_txid(&self) -> &[u8; 32];
    fn source_output_index(&self) -> u32;
    fn sequence(&self) -> u32;
    fn source_satoshis(&self) -> Option<u64>;
    fn source_locking_script(&self) -> Option<&LockingScript>;
    fn unlocking_script(&self) -> &UnlockingScript;
}

Context from a transaction input needed for script validation.

This trait abstracts the transaction input data needed by the Script module to validate spends. The Transaction module will implement this trait.

Required Methods

fn source_txid(&self) -> &[u8; 32]

The transaction ID of the UTXO being spent (32 bytes, internal byte order).

fn source_output_index(&self) -> u32

The index of the output being spent in the source transaction.

fn sequence(&self) -> u32

The sequence number of this input.

fn source_satoshis(&self) -> Option<u64>

The satoshi value of the UTXO being spent.

Returns None if the source transaction data is not available. This is required for sighash computation (BIP-143).

fn source_locking_script(&self) -> Option<&LockingScript>

The locking script of the UTXO being spent.

Returns None if the source transaction data is not available.

fn unlocking_script(&self) -> &UnlockingScript

The unlocking script for this input.
