Crate drop_guard [−] [src]
This crate gives a generic way to add a callback to any dropping value
You may use this for debugging values, see the struct documentation or the standalone examples.
Example:
extern crate drop_guard; use drop_guard::DropGuard; use std::thread::{spawn, sleep}; use std::time::Duration; fn main() { // The guard must have a name. `_` will drop it instantly, which would // lead to unexpected results let _g = DropGuard::new(spawn(move || { sleep(Duration::from_secs(2)); println!("println! from thread"); }) , |join_handle| join_handle.join().unwrap()); println!("Waiting for thread ..."); }
