Exception Handling

Comprehensive error handling with backtraces.

Enable Exception Handling

#![allow(unused)]
fn main() {
let mut config = LoggerConfig::default();
config.enable_exception_handling = true;
logger.configure(config);
}

Exception Callback

Handle exceptions with custom logic:

#![allow(unused)]
fn main() {
logger.add_exception_callback(|error, backtrace| {
    eprintln!("Exception occurred: {}", error);
    eprintln!("Backtrace:\n{}", backtrace);
    
    // Send to monitoring service
    // alert_team(&error);
});
}

Error Types

Logly uses LoglyError enum:

• IoError - File I/O errors
• ConfigError - Configuration errors
• SinkError - Sink operation errors
• GpuError - GPU-related errors
• FormatError - Formatting errors

Example

use logly::prelude::*;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let logger = Logger::new();
    
    logger.add_exception_callback(|error, backtrace| {
        eprintln!("Error: {}\n{}", error, backtrace);
    });
    
    logger.add_sink(SinkConfig::default())?;
    logger.info("Running".to_string())?;
    
    Ok(())
}
