Struct WasmSpendBuilder 

pub struct WasmSpendBuilder { /* private fields */ }

Implementations

impl WasmSpendBuilder

pub fn new( note: WasmNote, spend_condition: WasmSpendCondition, refund_lock: Option<WasmSpendCondition>, ) -> Result<Self, JsValue>

Create a new SpendBuilder with a given note and spend condition

pub fn fee(&mut self, fee: Nicks)

Set the fee of this spend

pub fn compute_refund(&mut self, include_lock_data: bool)

Compute refund from any spare assets, given refund_lock was passed

pub fn cur_refund(&self) -> Option<WasmSeed>

Get current refund

pub fn is_balanced(&self) -> bool

Checks whether note.assets = seeds + fee

This function needs to return true for TxBuilder::validate to pass

pub fn seed(&mut self, seed: WasmSeed) -> Result<(), JsValue>

Add seed to this spend

Seed is an output with a recipient (as defined by the spend condition).

Nockchain transaction engine will take all seeds with matching lock from all spends in the transaction, and merge them into one output note.

pub fn invalidate_sigs(&mut self)

Manually invalidate signatures

Each spend’s fee+seeds are bound to one or more signatures. If they get changed, the signature becomes invalid. This builder automatically invalidates signatures upon relevant modifications, but this functionality is provided nonetheless.

pub fn missing_unlocks(&self) -> Result<Vec<JsValue>, JsValue>

Get the list of missing “unlocks”

An unlock is a spend condition to be satisfied. For instance, for a Pkh spend condition, if the transaction is unsigned, this function will return a Pkh type missing unlock, with the list of valid PKH’s and number of signatures needed. This will not return PKHs that are already attatched to the spend (relevant for multisigs). For Hax spend condition, this will return any missing preimages. This function will return a list of not-yet-validated spend conditions.

pub fn add_preimage( &mut self, preimage_jam: &[u8], ) -> Result<Option<WasmDigest>, JsValue>

Attatch a preimage to this spend

pub fn sign(&mut self, signing_key_bytes: &[u8]) -> Result<bool, JsValue>

Sign the transaction with a given private key

Trait Implementations

impl From<SpendBuilder> for WasmSpendBuilder

fn from(builder: SpendBuilder) -> Self

Converts to this type from the input type.

impl From<WasmSpendBuilder> for JsValue

fn from(value: WasmSpendBuilder) -> Self

Converts to this type from the input type.

impl From<WasmSpendBuilder> for SpendBuilder

fn from(value: WasmSpendBuilder) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WasmSpendBuilder

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 WasmSpendBuilder

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 LongRefFromWasmAbi for WasmSpendBuilder

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmSpendBuilder>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmSpendBuilder

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 WasmSpendBuilder

fn none() -> Self::Abi

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

impl RefFromWasmAbi for WasmSpendBuilder

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmSpendBuilder>

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 WasmSpendBuilder

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmSpendBuilder>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WasmSpendBuilder

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for WasmSpendBuilder

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[WasmSpendBuilder]>

impl VectorIntoWasmAbi for WasmSpendBuilder

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi
