Enum Value

pub enum Value {
    I32(i32),
    I64(i64),
    F32(f32),
    F64(f64),
    FuncRef(Option<Func>),
    ExternRef(Option<ExternRef>),
}

Runtime representation of a value.

Wasm code manipulate values of the four basic value types: integers and floating-point data of 32 or 64 bit width each, respectively.

There is no distinction between signed and unsigned integer types. Instead, integers are interpreted by respective operations as either unsigned or signed in two’s complement representation.

Variants

I32(i32)

Value of 32-bit signed or unsigned integer.

I64(i64)

Value of 64-bit signed or unsigned integer.

F32(f32)

Value of 32-bit floating point number.

F64(f64)

Value of 64-bit floating point number.

FuncRef(Option<Func>)

An optional function reference.

ExternRef(Option<ExternRef>)

An optional external reference.

Implementations

impl Value

pub const fn ty(&self) -> ValueType

Returns the ValueType for this Value.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl<E: WasmEngine> From<&Value<E>> for Value

fn from(value: &Value<E>) -> Self

Converts to this type from the input type.

impl<E: WasmEngine> From<&Value> for Value<E>

fn from(value: &Value) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, o: &Self) -> 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.
