Cargo Documentation License

let (tx, rx) = flume::unbounded();

thread::spawn(move || (0..10).for_each(|i| { tx.send(i); }));

let received = rx
    .iter()
    .sum();

assert_eq!((0..10).sum(), received);

Why Flume?

  • Featureful: Unbounded, bounded and rendezvous queues
  • Fast: Always faster than std::sync::mpsc and sometimes crossbeam-channel
  • Safe: No unsafe code anywhere in the codebase!
  • Flexible: Sender and Receiver both implement Send + Sync + Clone
  • Familiar: Drop-in replacement for std::sync::mpsc
  • Capable: Additional features like MPMC support and send timeouts/deadlines
  • Simple: Few dependencies, minimal codebase, fast to compile
  • Asynchronous: async support, including mix 'n match with sync code
  • Ergonomic: Powerful select-like interface

Usage

To use Flume, place the following line under the [dependencies] section in your Cargo.toml:

flume = "x.y"

Benchmarks

Although Flume has its own extensive benchmarks, don't take it from here that Flume is quick. The following graph is from the crossbeam-channel benchmark suite.
