drop_guard

Use cases

Joining threads when they fall out of scope:

```rust 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::fromsecs(2)); println!("println! from thread"); }) , |joinhandle| joinhandle.join().unwrap());

println!("Waiting for thread ...");

} ```

Examples

Feel free to run the included examples:

bash cargo run --example rainbow cargo run --example thread cargo run --example threadpool
