✉️ Rust Channels §

= one way, thread-safe queue between threads, multiproducer, single-consumer pattern

How? §

Values that can be sent:

• Implement std::marker::Send: safe to pass by value
• Implement std::marker::Sync: safe to pass by non-mut reference

Normal channels §

• let (sender, receiver) = mpsc::channel()
• sender.send(item), receiver.recv() -> iterator
• Multiple:
  • senders: clone the sender
  • receivers: 🔒 Rust Mutex

Synchronous channels §

Channels, that have a fixed size (to avoid ever-growing backlog due to slow receiver)

• let (sender, receiver) = mpsc::sync_channel(size)
