Implementations

impl WasmValue

pub fn const_instr(&self) -> ConstInstruction

Get the type of a WasmValue

Trait Implementations

impl Clone for WasmValue

fn clone(&self) -> WasmValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasmValue

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

Formats the value using the given formatter.

impl From<f32> for WasmValue

fn from(i: f32) -> Self

Converts to this type from the input type.

impl From<f64> for WasmValue

fn from(i: f64) -> Self

Converts to this type from the input type.

impl From<i32> for WasmValue

fn from(i: i32) -> Self

Converts to this type from the input type.

impl From<i64> for WasmValue

fn from(i: i64) -> Self

Converts to this type from the input type.

impl From<u128> for WasmValue

fn from(i: u128) -> Self

Converts to this type from the input type.

impl PartialEq for WasmValue

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WasmValue> for f64

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WasmValue> for i32

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WasmValue> for i64

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<WasmValue> for u128

type Error = ()

The type returned in the event of a conversion error.

fn try_from(value: WasmValue) -> Result<Self, Self::Error>

Performs the conversion.
