Enum Val

pub enum Val {
    I32(i32),
    I64(i64),
    F32(f32),
    F64(f64),
    V128(i128),
    ExternRef(Option<ExternRef>),
}

Defines runtime values that a WebAssembly module can either consume or produce.

Variants

I32(i32)

32-bit integer.

Integers are not inherently signed or unsigned, their interpretation is determined by individual operations.

I64(i64)

64-bit integer.

Integers are not inherently signed or unsigned, their interpretation is determined by individual operations.

F32(f32)

32-bit floating-point data as defined by the IEEE 754-2019.

F64(f64)

64-bit floating-point data as defined by the IEEE 754-2019.

V128(i128)

128-bit vector of packed integer or floating-point data.

The packed data can be interpreted as signed or unsigned integers, single or double precision floating-point values, or a single 128 bit type. The interpretation is determined by individual operations.

ExternRef(Option<ExternRef>)

A reference to a host function.

FuncRef(None) is the null function reference, created by ref.null func in Wasm. A reference to opaque data in the wasm instance.

ExternRef(None) is the null external reference, created by ref.null extern in Wasm.

Trait Implementations

impl Debug for Val

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

Formats the value using the given formatter.

impl From<Val> for WasmValue

fn from(val: Val) -> Self

Converts to this type from the input type.

impl From<WasmValue> for Val

fn from(value: WasmValue) -> Self
