Enum wasmparser::ValType

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

Represents the types of values in a WebAssembly module.

Variants

I32

The value type is i32.

I64

The value type is i64.

F32

The value type is f32.

F64

The value type is f64.

V128

The value type is v128.

FuncRef

The value type is a function reference.

ExternRef

The value type is an extern reference.

Implementations

impl ValType

pub fn is_reference_type(&self) -> bool

Returns whether this value type is a “reference type”.

Only reference types are allowed in tables, for example, and with some instructions. Current reference types include funcref and externref.

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<'a> FromReader<'a> for ValType

fn from_reader(reader: &mut BinaryReader<'a>) -> Result<Self>

Attempts to read Self from the provided binary reader, returning an error if it is unable to do so.

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<ValType> 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.
