Use established logging libraries

Avoid using print statements (println!, eprintln!) or custom logging implementations for application logging. Instead, use established logging libraries like tracing that provide proper log levels, structured output, and configurable destinations.

Print statements bypass logging configuration and cannot be controlled at runtime. Custom logging implementations are error-prone and lack the features of mature libraries. Established logging libraries offer better performance, structured data support, and integration with monitoring systems.

Replace debug prints with appropriate log levels:

// Instead of this:
println!("🔒 SecurityManager::new() called - checking if security should be enabled");

// Use this:
tracing::debug!("SecurityManager::new() called - checking if security should be enabled");

For custom logging needs, extend existing logging infrastructure rather than creating new implementations:

// Instead of rolling your own:
pub fn log_debug_event(event: &str) {
    // custom file writing logic...
}

// Use tracing with appropriate configuration:
tracing::debug!(event = %event, "debug event occurred");

This ensures consistent logging behavior, proper log level control, and integration with the application’s logging configuration.
