thread_spawn
Write Rust functions that spawn threads and implicitly return JoinHandles.
#![feature(plugin, proc_macro)]
extern crate thread_spawn;
use thread_spawn::thread_spawn;
#[thread_spawn]
fn foo(a: u8, b: u8, (c, _): (u8, u8)) -> bool {
assert!(a + b + c == 5);
5 - c == b
}
fn main() {
let mut x = 0;
let mut y = 1;
let res = foo(x, y, (4, 0)).join(); // explicit join call
match res {
Ok(res) => println!("result: {:?}", res),
Err(err) => panic!("Thread panicked: {:?}", err),
}
}
Upsides:
- Automatically names the thread after the spawning function so you have improved error messages.
- Help wanted: Make the syntax `#[thread_spawn(name("thread {}", arg_or_expression)] work
- Mirrors the
async
keyword, conceptually. - Fewer keystrokes!
