Struct wasmtime::ExternRef

#[repr(transparent)]
pub struct ExternRef { /* fields omitted */ }

Represents an opaque reference to any data within WebAssembly.

Implementations

impl ExternRef

pub fn new<T>(value: T) -> ExternRef where
    T: 'static + Any + Send + Sync, 

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.

Note that this loads the reference count with a SeqCst ordering to synchronize with other threads.

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

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

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

impl Debug for ExternRef

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