Enum wasmparser::HeapType

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

A heap type.

Variants

Abstract

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

Fields

shared: bool

Whether the type is shared.

Introduced in the shared-everything-threads proposal.

ty: AbstractHeapType

The actual heap type.

Concrete(UnpackedIndex)

A concrete, user-defined type.

Introduced in the function-references proposal.

Implementations

impl HeapType

pub const FUNC: Self = _

Alias for an unshared func heap type.

pub const EXTERN: Self = _

Alias for an unshared extern 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<'a> FromReader<'a> for HeapType

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 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 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.
