Implementations

impl Constant

pub fn decode_from_base16(base16_bytes_str: String) -> Result<Constant, JsValue>

Decode from Base16-encoded ErgoTree serialized value

pub fn encode_to_base16(&self) -> String

Encode as Base16-encoded ErgoTree serialized value

pub fn from_i32(v: i32) -> Constant

Create from i32 value

pub fn to_i32(&self) -> Result<i32, JsValue>

Extract i32 value, returning error if wrong type

pub fn from_i64(v: &I64) -> Constant

Create from i64

pub fn to_i64(&self) -> Result<I64, JsValue>

Extract i64 value, returning error if wrong type

pub fn from_byte_array(v: &[u8]) -> Constant

Create from byte array

pub fn to_byte_array(&self) -> Result<Uint8Array, JsValue>

Extract byte array, returning error if wrong type

Trait Implementations

impl Clone for Constant

fn clone(&self) -> Constant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constant

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

Formats the value using the given formatter.

impl Eq for Constant

impl From<Constant> for Constant

fn from(c: Constant) -> Self

Performs the conversion.

impl FromWasmAbi for Constant

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 Constant

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 Constant

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 Constant

fn none() -> Self::Abi

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

impl PartialEq<Constant> for Constant

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

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

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

This method tests for !=.

impl RefFromWasmAbi for Constant

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Constant>

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 Constant

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Constant>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi
