Trait core::ops::Drop
[−]
[src]
pub trait Drop {
fn drop(&mut self);
}The Drop trait is used to run some code when a value goes out of scope.
This is sometimes called a 'destructor'.
Examples
A trivial implementation of Drop. The drop method is called when _x
goes out of scope, and therefore main prints Dropping!.
struct HasDrop; impl Drop for HasDrop { fn drop(&mut self) { println!("Dropping!"); } } fn main() { let _x = HasDrop; }
Required Methods
fn drop(&mut self)
A method called when the value goes out of scope.
