Module error_handler

Execution Error Handler

Defines all error types that can occur during VM execution and provides comprehensive error handling capabilities.

Error Categories

• Stack Errors: Underflow, overflow, invalid operations
• Type Errors: Invalid type conversions, unsupported operations
• Runtime Errors: General execution failures, exceptions
• Memory Errors: Heap allocation failures, invalid references
• Control Flow Errors: Invalid jumps, function call failures

Error Handling Strategy

The VM uses a comprehensive error handling strategy:

1. Immediate Detection: Errors are detected as soon as they occur
2. Detailed Information: Each error contains context about what went wrong
3. Recovery Options: Some errors can be recovered from automatically
4. User Feedback: Clear error messages for debugging

Usage

use jetcrab::vm::executor::error_handler::ExecutionError;

match some_operation() {
    Ok(result) => println!("Success: {:?}", result),
    Err(ExecutionError::StackUnderflow) => {
        eprintln!("Stack underflow occurred");
    }
    Err(ExecutionError::TypeError(msg)) => {
        eprintln!("Type error: {}", msg);
    }
    Err(e) => eprintln!("Other error: {:?}", e),
}
