Enum Type

#[repr(u8)]
pub enum Type {
    I32 = 0,

Variants

I32 = 0

Signed 32 bit integer.

I64 = 1

Signed 64 bit integer.

F32 = 2

Floating point 32 bit integer.

F64 = 3

Floating point 64 bit integer.

V128 = 4

A 128 bit number.

ExternRef = 5

A reference to opaque data in the Wasm instance.

FuncRef = 6

A reference to a Wasm function.

Implementations

impl Type

pub fn is_num(self) -> bool

Returns true if Type matches any of the numeric types. (e.g. I32, I64, F32, F64, V128).

pub fn is_ref(self) -> bool

Returns true if Type matches either of the reference types.

Trait Implementations

impl Archive for Type

type Archived = ArchivedType

The archived representation of this type.

type Resolver = TypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for Type

fn clone(&self) -> Type

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<Type, __D> for Archived<Type>

fn deserialize( &self, deserializer: &mut __D, ) -> Result<Type, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for Type

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

Formats the value using the given formatter.

impl Hash for Type

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 Type

fn eq(&self, other: &Type) -> 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<__S: Fallible + ?Sized> Serialize<__S> for Type

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for Type

impl Eq for Type

impl StructuralPartialEq for Type
