Struct SafeArcDyn 

pub struct SafeArcDyn<T: ?Sized> { /* private fields */ }

A safe, cloneable, droppable reference to a dyn trait object loaded from a dynamic library. Uses Arc-like retain/release for memory safety.

Implementations

impl<T: ?Sized> SafeArcDyn<T>

pub fn from_arc(value: Arc<T>) -> Self

Create from an Arc<T>. The Arc’s reference count is managed via the retain/release function pointers.

pub fn into_abi(self) -> AbiStableDynRef

Get the ABI-stable representation (for exporting from a plugin).

pub unsafe fn from_abi(raw: AbiStableDynRef) -> Self

Reconstruct from an ABI-stable representation (for loading in host).

Safety

raw must have been created by SafeArcDyn::<T> or compatible code.

pub unsafe fn trait_ref(&self) -> &T

Get a reference to the trait object.

Safety

The stored fat pointer must be valid for the lifetime of this reference.

Trait Implementations

impl<T: ?Sized> Clone for SafeArcDyn<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: ?Sized> Drop for SafeArcDyn<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
