Trait OnDropCallback 

pub trait OnDropCallback: Send + 'static {
    // Required method
    fn on_drop(self);
}

Available on crate feature on-early-drop only.

Callback fired exactly once when an early-drop event is observed.

FnOnce() + Send + 'static closures implement this via a blanket impl.

Panics

Implementations must not panic. Callbacks fire from Drop; panicking during a drop that occurs while another panic is unwinding aborts the process. The crate’s built-in callbacks are panic-free.

Required Methods

fn on_drop(self)

Fire the callback. Consumes self.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
