Enum wasmtime::ValType

pub enum ValType {
    I32,
    I64,
    F32,
    F64,
    V128,
    FuncRef,
    ExternRef,
}

A list of all possible value types in WebAssembly.

Variants

I32

Signed 32 bit integer.

I64

Signed 64 bit integer.

F32

Floating point 32 bit integer.

F64

Floating point 64 bit integer.

V128

A 128 bit number.

FuncRef

A reference to a Wasm function.

ExternRef

A reference to opaque data in the Wasm instance.

Implementations

impl ValType

pub fn is_num(&self) -> bool

Returns true if ValType matches any of the numeric types. (e.g. I32, I64, F32, F64).

pub fn is_ref(&self) -> bool

Returns true if ValType matches either of the reference types.

Trait Implementations

impl Clone for ValType

fn clone(&self) -> ValType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValType

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

Formats the value using the given formatter.

impl Display for ValType

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

Formats the value using the given formatter.

impl Hash for ValType

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

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 ValType

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

This method tests for self and other values to be equal, and is used by ==.

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

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