Module util 

Utility module providing helper types and macros for the I/O event system.

This module contains various utility components that support the event system:

• Macros for creating subscribers
• Type aliases for common result types
• Error handling utilities
• Iterator implementations for error handling

Examples

use ioevent::prelude::*;

// Using the create_subscriber macro
#[subscriber]
async fn handle_event(state: State<()>, event: MyEvent) -> Result {
    println!("Event received: {:?}", event);
    Ok(())
}

let subscriber = create_subscriber!(handle_event);

For more examples and detailed usage, see the individual component documentation.

• Macros for creating surs
• Type aliases for common result types
