Represents an opaque reference to any data within WebAssembly.

Implementations

impl ExternRef

pub fn new<T>(value: T) -> ExternRef

where T: 'static + Any,

Creates a new instance of ExternRef wrapping the given value.

pub fn data(&self) -> &dyn Any

Get the underlying data for this ExternRef.

pub fn strong_count(&self) -> usize

Get the strong reference count for this ExternRef.

pub fn ptr_eq(&self, other: &ExternRef) -> bool

Does this ExternRef point to the same inner value as other?0

This is only pointer equality, and does not run any inner value’s Eq implementation.
