Enum WasmValueType

#[non_exhaustive]
#[repr(u8)]
pub enum WasmValueType {
    I32 = 0,
    I64 = 1,
    F32 = 2,
    F64 = 3,
    V128 = 4,
}

The type of a WASM value represented at runtime for use with the wasix closures API.

For now only number types are supported, but this may be extended in the future to include references

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

I32 = 0

A i32 parameter.

I64 = 1

A i64 parameter.

F32 = 2

A f32 parameter.

F64 = 3

A f64 parameter.

V128 = 4

A v128 parameter.

Trait Implementations

impl Clone for WasmValueType

fn clone(&self) -> WasmValueType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmValueType

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

Formats the value using the given formatter.

impl Hash for WasmValueType

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WasmValueType

fn eq(&self, other: &WasmValueType) -> 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.

impl TryFrom<Type> for WasmValueType

type Error = ()

The type returned in the event of a conversion error.

fn try_from( value: Type, ) -> Result<WasmValueType, <WasmValueType as TryFrom<Type>>::Error>

Performs the conversion.

impl TryFrom<u8> for WasmValueType

type Error = TryFromPrimitiveError<WasmValueType>

The type returned in the event of a conversion error.

fn try_from( number: u8, ) -> Result<WasmValueType, TryFromPrimitiveError<WasmValueType>>

Performs the conversion.

impl TryFromPrimitive for WasmValueType

const NAME: &'static str = "WasmValueType"

type Primitive = u8

type Error = TryFromPrimitiveError<WasmValueType>

fn try_from_primitive( number: <WasmValueType as TryFromPrimitive>::Primitive, ) -> Result<WasmValueType, TryFromPrimitiveError<WasmValueType>>

impl ValueType for WasmValueType

fn zero_padding_bytes(&self, _bytes: &mut [MaybeUninit<u8>])

This method is passed a byte slice which contains the byte representation of self. It must zero out any bytes which are uninitialized (e.g. padding bytes).

impl Copy for WasmValueType

impl Eq for WasmValueType

impl StructuralPartialEq for WasmValueType
