Struct bsv_wasm::transaction::Transaction

pub struct Transaction { /* fields omitted */ }

Implementations

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

    &mut self,
    priv_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>

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a copy 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 From<Transaction> for JsValue

fn from(value: Transaction) -> Self

Performs the conversion.

impl FromWasmAbi for Transaction

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Transaction

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for Transaction

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Transaction

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq<Transaction> for Transaction

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl RefFromWasmAbi for Transaction

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Transaction>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Transaction

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Transaction>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

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.

impl WasmDescribe for Transaction

fn describe()
