👎Deprecated since 0.24.0: please use SigHashCache instead

Parts of a sighash which are common across inputs or signatures, and which are sufficient (in conjunction with a private key) to sign the transaction

Fields

hash_prevouts: SigHash

👎Deprecated since 0.24.0: please use SigHashCache instead

Hash of all the previous outputs

hash_sequence: SigHash

👎Deprecated since 0.24.0: please use SigHashCache instead

Hash of all the input sequence nos

hash_outputs: SigHash

👎Deprecated since 0.24.0: please use SigHashCache instead

Hash of all the outputs in this transaction

Implementations

impl SighashComponents

pub fn new(tx: &Transaction) -> SighashComponents

Compute the sighash components from an unsigned transaction and auxiliary information about its inputs. For the generated sighashes to be valid, no fields in the transaction may change except for script_sig and witnesses.

pub fn sighash_all( &self, txin: &TxIn, script_code: &Script, value: u64, ) -> SigHash

Compute the BIP143 sighash for a SIGHASH_ALL signature for the given input.

Trait Implementations

impl Clone for SighashComponents

fn clone(&self) -> SighashComponents

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SighashComponents

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

Formats the value using the given formatter.

impl PartialEq for SighashComponents

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

Tests for self and other values to be equal, and is used by ==.

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

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