Implementations

impl BigInt

pub fn to_cbor_bytes(&self) -> Vec<u8>

• Serialize this type to CBOR bytes
• This type type supports encoding preservation so this will preserve round-trip CBOR formats.
• If created from scratch the CBOR will be canonical.

pub fn from_cbor_bytes(cbor_bytes: &[u8]) -> Result<BigInt, JsError>

• Create this type from CBOR bytes

pub fn to_cbor_hex(&self) -> String

• Serialize this type to CBOR bytes encoded as a hex string (useful for working with CIP30).
• This type type supports encoding preservation so this will preserve round-trip CBOR formats.
• If created from scratch the CBOR will be canonical.

pub fn from_cbor_hex(cbor_bytes: &str) -> Result<BigInt, JsError>

• Create this type from the CBOR bytes encoded as a hex string.
• This is useful for interfacing with CIP30

impl BigInt

pub fn to_json(&self) -> Result<String, JsError>

pub fn to_js_value(&self) -> Result<JsValue, JsError>

pub fn from_json(json: &str) -> Result<BigInt, JsError>

impl BigInt

pub fn from_int(x: &Int) -> Self

pub fn from_str(s: &str) -> Result<BigInt, JsError>

pub fn to_str(&self) -> String

pub fn as_u64(&self) -> Option<u64>

Converts to a u64 Returns None if the number was negative or too big for a u64

pub fn as_int(&self) -> Option<Int>

Converts to an Int Returns None when the number is too big for an Int (outside +/- 64-bit unsigned) Retains encoding info if the original was encoded as an Int

Trait Implementations

impl AsRef<BigInt> for BigInt

fn as_ref(&self) -> &BigInt

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for BigInt

fn clone(&self) -> BigInt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BigInt

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

Formats the value using the given formatter.

impl From<BigInt> for BigInt

fn from(native: BigInt) -> Self

Converts to this type from the input type.

impl From<BigInt> for JsValue

fn from(value: BigInt) -> Self

Converts to this type from the input type.

impl FromWasmAbi for BigInt

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 Into<BigInt> for BigInt

fn into(self) -> BigInt

Converts this type into the (usually inferred) input type.

impl IntoWasmAbi for BigInt

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 BigInt

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 BigInt

fn none() -> Self::Abi

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

impl RefFromWasmAbi for BigInt

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, BigInt>

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 BigInt

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, BigInt>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for BigInt

fn describe()
