Remove `Ipv4Addr::is_ietf_protocol_assignment` This PR removes the unstable method `Ipv4Addr::is_ietf_protocol_assignment`, as I suggested in https://github.com/rust-lang/rust/issues/85612#issuecomment-847863404. The method was added in #60145, as far as I can tell primarily for the implementation of `Ipv4Addr::is_global` (addresses reserved for IETF protocol assignment are not globally reachable unless otherwise specified). The method was added in 2019, but I haven't been able to find any open-source code using this method so far. I'm also having a hard time coming up with a usecase for specifically this method; knowing that an address is reserved for future protocols doesn't allow you to do much with it, especially since now some of those addresses are indeed assigned to a protocol and have their own behaviour (and might even be defined to be globally reachable, so if that is what you care about it is always more accurate to call `!is_global()`, instead of `is_ietf_protocol_assignment()`). Because of these reasons, I propose removing the method (or alternatively make it a private helper for `is_global`) and also not introduce `Ipv6Addr::is_ietf_protocol_assignment` and `IpAddr::is_ietf_protocol_assignment` in the future. |
