I64

Signed 64 bit integer.

F32

Floating point 32 bit integer.

F64

ExternRef

FuncRef

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 = Type

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.

unsafe fn resolve( &self, pos: usize, resolver: <Self as Archive>::Resolver, out: *mut <Self as Archive>::Archived )

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

impl<__C: ?Sized> CheckBytes<__C> for Type

type Error = EnumCheckError<u8>

The error that may result from checking the type.

unsafe fn check_bytes<'__bytecheck>( value: *const Self, context: &mut __C ) -> Result<&'__bytecheck Self, EnumCheckError<u8>>

Checks whether the given pointer points to a valid value within the given context.

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::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<Type> for Type

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

impl<__S: Fallible + ?Sized> Serialize<__S> for Type

fn serialize( &self, serializer: &mut __S ) -> Result<<Self as Archive>::Resolver, __S::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 StructuralEq for Type

impl StructuralPartialEq for Type
