Struct Dropper 

pub struct Dropper<T>
where
    T: AsyncDrop,
{ /* private fields */ }

A wrapper that calls AsyncDrop::async_drop when dropped.

Dropper<T> dereferences to T, so the wrapped value can be used transparently. On drop, it spawns a dedicated thread with a short-lived Tokio runtime to drive the cleanup future to completion. This avoids deadlocks when the Dropper is dropped inside a single-threaded async executor.

Panics

Panics if the internal Tokio runtime cannot be created.

Implementations

impl<T> Dropper<T>

where T: AsyncDrop,

pub fn new(inner: T) -> Self

Wraps inner so that its AsyncDrop::async_drop implementation is called automatically when this Dropper is dropped.

Trait Implementations

impl<T> Deref for Dropper<T>

where T: AsyncDrop + 'static,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for Dropper<T>

where T: AsyncDrop + 'static,

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> Drop for Dropper<T>

where T: AsyncDrop,

fn drop(&mut self)

Executes the destructor for this type.
