Trait Implementations

impl Clone for HeapType

fn clone(&self) -> HeapType

Returns a duplicate 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 From<HeapType> for HeapType

fn from(value: HeapType) -> Self

Converts a HeapType into a wasm_encoder::HeapType. Shared types are not supported, so defaults to false for Abstract types.

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.

impl TryFrom<HeapType> for HeapType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(ty: HeapType) -> Result<Self>

Performs the conversion.

impl Copy for HeapType

impl Eq for HeapType

impl StructuralPartialEq for HeapType
