events

High-performance event signaling primitives for concurrent environments.

This crate provides lightweight, efficient signaling mechanisms for communicating between different parts of an application. The API is designed to be simple to use while offering high performance in concurrent scenarios.

Both single-threaded and thread-safe variants are available:

• OnceEvent<T>, OnceSender<T, R>, OnceReceiver<T, R> - Thread-safe variants
• LocalOnceEvent<T>, LocalOnceSender<T, R>, LocalOnceReceiver<T, R> - Single-threaded variants

use events::OnceEvent;

// Create a thread-safe event for passing a string message
let event = OnceEvent::<String>::new();
let (sender, receiver) = event.bind_by_ref();

// Send a message through the event
sender.send("Hello, World!".to_string());

// Receive the message (await since it's async)
let message = receiver.await.unwrap();
assert_eq!(message, "Hello, World!");

This is part of the Folo project that provides mechanisms for high-performance hardware-aware programming in Rust.
