Function std::mem::dropStable

pub fn drop<T>(_x: T)

Disposes of a value.

This function can be used to destroy any value by allowing drop to take ownership of its argument.

Examples

fn main() { use std::cell::RefCell; let x = RefCell::new(1); let mut mutable_borrow = x.borrow_mut(); *mutable_borrow = 1; drop(mutable_borrow); // relinquish the mutable borrow on this slot let borrow = x.borrow(); println!("{}", *borrow); }

use std::cell::RefCell;

let x = RefCell::new(1);

let mut mutable_borrow = x.borrow_mut();
*mutable_borrow = 1;

drop(mutable_borrow); // relinquish the mutable borrow on this slot

let borrow = x.borrow();
println!("{}", *borrow);
