Struct Transaction 

pub struct Transaction { /* private fields */ }

Implementations

impl Transaction

pub fn match_output(&self, criteria: &MatchCriteria) -> Option<usize>

Returns the first output index that matches the given parameters, returns None or null if not found.

pub fn match_outputs(&self, criteria: &MatchCriteria) -> Vec<usize>

Returns a list of outputs indexes that match the given parameters

pub fn match_input(&self, criteria: &MatchCriteria) -> Option<usize>

Returns the first input index that matches the given parameters, returns None or null if not found.

pub fn match_inputs(&self, criteria: &MatchCriteria) -> Vec<usize>

Returns a list of input indexes that match the given parameters

impl Transaction

pub fn hash_inputs(&mut self, sighash: SigHash) -> Vec<u8>

(hashPrevouts) https://github.com/bitcoincashorg/bitcoincash.org/blob/master/spec/replay-protected-sighash.md Checks the hash cache to see if there already are hashed inputs, otherwise calculates the hash and adds it to the cache.

Logic:

• If SigHash does not contain ANYONECANPAY, SHA256d all input outpoints
• Else 32 bytes of zeroes

impl Transaction

pub fn verify(&self, pub_key: &PublicKey, sig: &SighashSignature) -> bool

impl Transaction

pub fn sign( &mut self, priv_key: &PrivateKey, sighash: SigHash, n_tx_in: usize, unsigned_script: &Script, value: u64, ) -> Result<SighashSignature, BSVErrors>

pub fn sign_with_k( &mut self, priv_key: &PrivateKey, ephemeral_key: &PrivateKey, sighash: SigHash, n_tx_in: usize, unsigned_script: &Script, value: u64, ) -> Result<SighashSignature, BSVErrors>

pub fn sighash_preimage( &mut self, sighash: SigHash, n_tx_in: usize, unsigned_script: &Script, value: u64, ) -> Result<Vec<u8>, BSVErrors>

impl Transaction

Platform Agnostic Functions ie. Don’t need Result<T, E>

pub fn default() -> Transaction

pub fn set_version(&mut self, version: u32) -> Transaction

pub fn set_nlocktime(&mut self, n_locktime: u32) -> Transaction

pub fn insert_output(&mut self, index: usize, output: &TxOut)

pub fn set_input(&mut self, index: usize, input: &TxIn)

pub fn set_output(&mut self, index: usize, output: &TxOut)

pub fn is_coinbase_impl(&self) -> bool

pub fn satoshis_in(&self) -> Option<u64>

XT Method: Returns the combined sum of all input satoshis. If any of the inputs dont have satoshis defined, this returns None or null

pub fn satoshis_out(&self) -> u64

Returns the combined sum of all output satoshis.

impl Transaction

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl Default for Transaction

fn default() -> Transaction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Transaction

fn eq(&self, other: &Transaction) -> 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.

impl Serialize for Transaction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
