global-channel

global-channel is a lightweight Rust crate that provides a simple way to define and use global, static channels for message passing. It supports both bounded and unbounded channels, powered by crossbeam-channel.

Features

• Define static, global channels with minimal boilerplate.
• Bounded and unbounded channels.
• Safe initialization using std::sync::Once.
• Highly performant with crossbeam-channel.

Usage

Create and use a global channel with the global_channel! macro:

use global_channel::global_channel;

global_channel!(my_channel, Some(10), u32); // Bounded channel with capacity 10

fn main() {
    let tx = my_channel_tx();
    let rx = my_channel_rx();

    tx.send(42).unwrap();
    println!("Received: {}", rx.recv().unwrap());
}

For an unbounded channel:

global_channel!(unbounded_channel, None, String);

Basic Example

use global_channel::global_channel;

global_channel!(example_channel, None, i32);

fn main() {
    let tx = example_channel_tx();
    let rx = example_channel_rx();

    tx.send(100).unwrap();
    assert_eq!(rx.recv().unwrap(), 100);
}
