Struct HeapRef 

pub struct HeapRef(/* private fields */);

Reference to a heap-allocated object.

HeapRef is an opaque handle that identifies an object on the managed heap. It is used with ManagedHeap to access strings, arrays, and object instances.

Equality

Two HeapRef values are equal if they point to the same heap object. This implements reference equality semantics.

Implementations

impl HeapRef

pub fn new(id: u64) -> Self

Creates a new heap reference with the given ID.

This is typically called by ManagedHeap when allocating new objects.

pub fn id(&self) -> u64

Returns the internal ID of this heap reference.

Trait Implementations

impl Clone for HeapRef

fn clone(&self) -> HeapRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeapRef

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

Formats the value using the given formatter.

impl Display for HeapRef

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

Formats the value using the given formatter.

impl From<HeapRef> for EmValue

fn from(value: HeapRef) -> Self

Converts to this type from the input type.

impl Hash for HeapRef

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 HeapRef

fn eq(&self, other: &HeapRef) -> 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<&EmValue> for HeapRef

type Error = EmulationError

The type returned in the event of a conversion error.

fn try_from(value: &EmValue) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<EmValue> for HeapRef

type Error = EmulationError

The type returned in the event of a conversion error.

fn try_from(value: EmValue) -> Result<Self, Self::Error>

Performs the conversion.
