Enum ValType

pub enum ValType {
    I32,
    I64,
    F32,
    F64,
    V128,
    Ref(RefType),
}

The type of a core WebAssembly value.

Variants

I32

The i32 type.

I64

The i64 type.

F32

The f32 type.

F64

The f64 type.

V128

The v128 type.

Part of the SIMD proposal.

Ref(RefType)

A reference type.

The funcref and externref type fall into this category and the full generalization here is due to the implementation of the function-references proposal.

Implementations

impl ValType

pub fn is_numeric(&self) -> bool

Is this a numeric value type?

pub fn is_vector(&self) -> bool

Is this a vector type?

pub fn is_reference(&self) -> bool

Is this a reference type?

impl ValType

pub const FUNCREF: ValType = _

Alias for the funcref type in WebAssembly

pub const EXTERNREF: ValType = _

Alias for the externref type in WebAssembly

pub const EXNREF: ValType = _

Alias for the exnref type in WebAssembly

pub fn is_defaultable(&self) -> bool

Is this value defaultable?

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 Encode for ValType

fn encode(&self, sink: &mut Vec<u8>)

Encode the type into the given byte sink.

impl From<RefType> for ValType

fn from(ty: RefType) -> ValType

Converts to this type from the input type.

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 Ord for ValType

fn cmp(&self, other: &ValType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ValType

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

fn partial_cmp(&self, other: &ValType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<ValType> for ValType

Available on crate feature wasmparser only.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(val_ty: ValType) -> Result<Self, Self::Error>

Performs the conversion.
