 The `ze_` prefix is used for the API that is not part of the core zenoh API. There is no guarantee that
 these functions and types are available everywhere. However, when they are provided, they should
 have the same prototype and behavior across all implementations. Typically, these are functions and types
 provided by the `zenoh-ext` Rust library for zenoh-c and are not available in zenoh-pico. However, the data
