Describe a scenario where creating a custom error type would be beneficial in a Go application.
- When dealing with standard library errors, which cover all use cases.
- When adding context information to errors is unnecessary.
- When multiple errors need to be handled using a single error type.
- When differentiating between specific errors is required.
Creating a custom error type in Go is beneficial when you need to differentiate between specific errors and handle them differently. For example, in a file handling application, you might create custom error types like FileNotFoundError or PermissionDeniedError to provide more meaningful error messages and take specific actions based on the error type. This improves error handling and debugging in your application.
