Trait TryDrop

pub trait TryDrop: Sized {
    // Required method
    fn try_drop(self) -> Result<(), Self>;
}

A type for which some values make sense to be able to drop without further consideration.

Required Methods

fn try_drop(self) -> Result<(), Self>

Drop an instance cleanly. Only works if its value represents “no-operation”.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
