pub struct OnDrop<F>(/* private fields */)
where
    F: FnOnce();

A utility struct that runs a cleanup function when dropped.

Implementations

impl<F> OnDrop<F>

where F: FnOnce() + 'static,

pub const fn new(f: F) -> Self

Creates a new OnDrop that will call the function when dropped.

pub fn attach(guard: impl WatcherGuard, f: F) -> impl WatcherGuard

Attaches a cleanup function to a guard.

Trait Implementations

impl<F> Debug for OnDrop<F>

where F: FnOnce() + Debug,

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

Formats the value using the given formatter.

impl<F> Drop for OnDrop<F>

where F: FnOnce(),

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.
