🔬 This is a nightly-only experimental API. (`unix_socket_ancillary_data` #76915)
This is supported on Unix only.

The error type which is returned from parsing the type a control message.

## Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
