rustHow to drop a closure in Rust
Dropping a closure in Rust is done by calling the drop function on the closure. This will deallocate any resources associated with the closure. For example, the following code creates a closure and then drops it:
let mut closure = || println!("Hello, world!");
drop(closure);The drop function takes a mutable reference to the closure, so it can be used to deallocate any resources associated with the closure. After the drop function is called, the closure is no longer valid and cannot be used.
