Enum wasm_encoder::HeapType

pub enum HeapType {
    Abstract {
        shared: bool,
        ty: AbstractHeapType,
    },
    Concrete(u32),
}

Part of the function references proposal.

Variants

Abstract

An abstract heap type; e.g., anyref.

Fields

shared: bool

Whether the type is shared.

ty: AbstractHeapType

The actual heap type.

Concrete(u32)

A concrete Wasm-defined type at the given index.

Implementations

impl HeapType

pub const ANY: Self = _

Alias for the unshared any heap type.

pub const FUNC: Self = _

Alias for the unshared func heap type.

pub const EXTERN: Self = _

Alias for the unshared extern heap type.

pub const I31: Self = _

Alias for the unshared i31 heap type.

Trait Implementations

impl Clone for HeapType

fn clone(&self) -> HeapType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeapType

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

Formats the value using the given formatter.

impl Encode for HeapType

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

Encode the type into the given byte sink.

impl Hash for HeapType

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 HeapType

fn cmp(&self, other: &HeapType) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for HeapType

fn eq(&self, other: &HeapType) -> 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 HeapType

fn partial_cmp(&self, other: &HeapType) -> 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<HeapType> for HeapType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(heap_type: HeapType) -> Result<Self, Self::Error>

Performs the conversion.
