What, exactly, is the "ip feature"? Could you link to the RustDoc(s) of the specific things that are supposed to be reviewed? |

I think "ip feature" in this context refers to things annotated with |
I don't mean to be rude, but that's just a restating my question as the answer. if you want people to actually give feedback on the proposal, it should be easier to understand what the proposal is. In this case, it is pretty difficult to tell what is being proposed because the module mixes stable and unstable features. I noticed that a large part of this module could work in It also seems odd that |
|
@briansmith I don't think that's being rude, there's just tension here between "we've been doing this a while so we're a bit short" and "newer people might not know what that is." @SimonSapin leaned a bit towards a literal explanation, but you're right to point out that more detail is good. I read @alexcrichton 's comment as:
http://doc.rust-lang.org/std/net/struct.Ipv4Addr.html and http://doc.rust-lang.org/std/net/struct.Ipv6Addr.html <- all the stuff here that is
http://doc.rust-lang.org/std/net/struct.Ipv6Addr.html#method.multicast_scope is the only one I see that's unstable. |
|
FWIW, I filed #29221 a while ago, which would make tracking down what these tracking issues refer to slightly easier. |
|
Yes, to be concrete, I was proposing stabilizing:
Note that this is all pending actually verifying that these are standard properties of the respective IP address space and are well known with canonical implementations. I believe they fit this requirement already but would like to double-check.
Yeah these things can certainly move around over time (it's backwards compatible to move them at a later date). I'd be a little wary of putting things in core "just because" without a concrete purpose, and these kinda fall into the category I'd be wary of. For example the internal representation of each of these primitives is the
Method resolution favors inherent methods (methods defined on the type itself) over trait methods (e.g. impl'd traits plus the trait being in scope), so in that sense we're covered to add a trait at a future date. That being said the standard library doesn't have too many traits like this for abstracting between one or two types, so I would personally want to hold off on this extension for now. A possible alternative, however, could be adding the common set of methods to |
|
A couple of issues I have noticed with what we have:
On a more general note, might some of these functions need to be updated in the future if new ranges are assigned? How would that be handled? |
|
Ah I unfortunately did not have time to do an audit of these APIs this cycle, so when the libs team talked about this during triage today the conclusion was to punt this to next cycle, I hope to have the time to investigate it then and incorportate @ollie27's suggestions! |
|
🔔 This issue is now yet again entering its final comment period 🔔 Hopefully I get a chance to researching this API this time around! |
|
Better late than never! -- my analysis: Of the ipv4 properties, there's more listed on wikipedia at least, for example:
These sound relatively obscure (at least to me) though, so it seems fine that we don't add them just yet. In terms of what we currently have:
Like with ipv4 we're missing some ipv6 properties (according to RFC 6890):
Of the ipv6 methods:
From this I'm comfortable stabilizing the checked methods (they've got verified names and implementations at least), but I would personally want some more verification of the unchecked methods before stabilizing. |
Sounds like a good start. The |

The libs team discussed this during triage yesterday and the decision was to stabilize the methods I've checked above |

Stabilize `Ipv6Addr::to_ipv4_mapped` CC rust-lang/rust#27709 (tracking issue for the `ip` feature which contains more functions) The function `Ipv6Addr::to_ipv4` is bad because it also returns an IPv4 address for the IPv6 loopback address `::1`. Stabilize `Ipv6Addr::to_ipv4_mapped` so we can recommend that function instead.

Hi everyone, The following concerns mostly I took the ipcheck tool[1] (which gave us some very useful data two years ago[2]) and modified it slightly to:
I present you two tables. The content is collapsed because of its length, you'll have to click on the arrows to see everything. Table 1. The status quo as of today (Rust nightly, Python versions as specified, Go 1.21.5)
Table 2. Patched Rust, patched CPython, regular Go.
In table 1 you'll see some Rust/Python disagreement in the following ranges: You'll also notice that starting with version 3.10 Python started to interpret IPv4-mapped IPv6 addresses as their IPv4 counterparts for the purposes of evaluating I consider both Rust and Python implementations somewhat buggy, sometimes buggy in the same way (for example when it comes to the In table 2 we have Rust/Python/Go comparison where
With the patches in place Rust and Python are in almost perfect agreement on the With the Rust patch the number of Rust/Go disagreements decreases by 1 (I think) but the nature of the disagreements changes (in both ways, it's roughly equalized). The implementation I propose is consistent with what's proposed by @tcoratger above (#27709 (comment)). The tables don't capture the difference in [1] https://github.com/rust-lang/libs-team/tree/main/tools/ipcheck |

looking forward to stabilisation of could theses simple convenience methods be included? possibly also on impl IpAddr {
pub fn ipv4(&self) -> Option<&Ipv4Addr> {
match self {
IpAddr::V4(ip) => Some(ip),
IpAddr::V6(_) => None,
}
}
pub fn ipv6(&self) -> Option<&Ipv6Addr> {
match self {
IpAddr::V4(_) => None,

core/net: add Ipv[46]Addr::from_octets, Ipv6Addr::from_segments.
Adds:
- `Ipv4Address::from_octets([u8;4])`
- `Ipv6Address::from_octets([u8;16])`
- `Ipv6Address::from_segments([u16;8])`
equivalent to the existing `From` impls.
Advantages:
- Consistent with `to_bits, from_bits`.
- More discoverable than the `From` impls.
- Helps with type inference: it's common to want to convert byte slices to IP addrs. If you try this
```rust
fn foo(x: &[u8]) -> Ipv4Addr {
Ipv4Addr::from(foo.try_into().unwrap())
}
```
it [doesn't work](https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=0e2873312de275a58fa6e33d1b213bec). You have to write `Ipv4Addr::from(<[u8;4]>::try_from(x).unwrap())` instead, which is not great. With `from_octets` it is able to infer the right types.
Found this while porting [smoltcp](https://github.com/smoltcp-rs/smoltcp/) from its own IP address types to the `core::net` types.

The below is a list of methods left to be stabilized under the
ipfeature. The path forward today is unclear; if you'd like to push through any method on here the libs team is interested in a PR with links to the associated RFCs or other official documentation.

Unresolved Questions
From @KodrAus in #76098 (comment):
Ipv6Addr::is_unicast_*methods with aIpv6Addr::unicast_scopemethod that returns aIpv6UnicastScopeenum (Stabilize the "IP" feature #76098 (comment))?Ipv6Addr::to_ipv4to ignore deprecated IPv4-compatible addresses, or deprecate the whole method in favor of the more correctIpv6Addr::to_ipv4_mappedmethod (Stabilize the "IP" feature #76098 (comment))?Ipv6Addr::is_*methods now properly considering mapped (non-deprecated) IPv4 addresses? I'd personally be comfortable considering the old behavior a bug.The text was updated successfully, but these errors were encountered:
