}

A trait for application error types that can be converted into UDS Negative Response Codes (NRCs).

The server state machine uses this to construct NRC responses without knowing the application’s error type internals. The application defines the mapping via Into<u8>.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
