Struct Rational

pub struct Rational(/* private fields */);

Implementations

impl Rational

pub fn from_base10_f32(f: f32) -> Self

Converts base 10 floats to SubCoin. This is the format used by blockfrost for ex units Warning: If the passed in float was not meant to be base 10 this might result in a slightly inaccurate fraction.

impl Rational

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 to_canonical_cbor_bytes(&self) -> Vec<u8>

• Serialize this type to CBOR bytes using canonical CBOR encodings

pub fn from_cbor_bytes(cbor_bytes: &[u8]) -> Result<Rational, 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 to_canonical_cbor_hex(&self) -> String

• Serialize this type to CBOR bytes using canonical CBOR encodings as hex bytes

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

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

Trait Implementations

impl AsRef<Rational> for Rational

fn as_ref(&self) -> &Rational

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

impl Clone for Rational

fn clone(&self) -> Rational

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rational

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

Formats the value using the given formatter.

impl From<Rational> for JsValue

fn from(value: Rational) -> Self

Converts to this type from the input type.

impl From<Rational> for Rational

fn from(native: Rational) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Rational

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<Rational> for Rational

fn into(self) -> Rational

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

impl IntoWasmAbi for Rational

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 Rational

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<Rational>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for Rational

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 Rational

fn none() -> Self::Abi

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

impl RefFromWasmAbi for Rational

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<Rational>

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 Rational

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<Rational>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for Rational

type Error = JsValue

The type returned in the event of a conversion error.

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

Performs the conversion.

impl VectorFromWasmAbi for Rational

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

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

impl VectorIntoJsValue for Rational

fn vector_into_jsvalue(vector: Box<[Rational]>) -> JsValue
