Tracking Issue for IP address prefixes

[CDirkx]

This is the tracking issue for IP address prefixes such as 192.0.2.0/24.
The feature gate for the issue is #![feature(ip_prefix)].

Overview

Ipv4AddrPrefix

#[derive(Copy, PartialEq, Eq, Clone, Hash)]
pub struct Ipv4AddrPrefix {
    address: Ipv4Addr,
    len: u8,
}

impl Ipv4AddrPrefix {
    pub const fn new(address: Ipv4AddrPrefix, len: u32) -> Result<Ipv4AddrPrefix, InvalidPrefixError>;
    pub const fn address(&self) -> Ipv4Addr;
    pub const fn len(&self) -> u32;
    pub const fn contains(&self, address: &Ipv4Addr) -> bool;
}

impl Debug for Ipv4AddrPrefix  {}
impl Display for Ipv4AddrPrefix  {}
impl From<Ipv4Addr> for Ipv4AddrPrefix  {}
impl FromStr for Ipv4AddrPrefix  {}

Ipv6AddrPrefix

#[derive(Copy, PartialEq, Eq, Clone, Hash)]
pub struct Ipv6AddrPrefix {
    address: Ipv6Addr,
    len: u8,
}

impl Ipv6AddrPrefix {
    pub const fn new(address: Ipv6AddrPrefix, len: u32) -> Result<Ipv6AddrPrefix, InvalidPrefixError>;
    pub const fn address(&self) -> Ipv6Addr;
    pub const fn len(&self) -> u32;
    pub const fn contains(&self, address: &Ipv6Addr) -> bool;
}

impl Debug for Ipv6AddrPrefix  {}
impl Display for Ipv6AddrPrefix  {}
impl From<Ipv6Addr> for Ipv6AddrPrefix  {}
impl FromStr for Ipv6AddrPrefix  {}

The feature tracked by this issue never got merged. I'll close the tracking issue since this is not tracking any work at the moment, but we can reopen (or create a new one) if someone picks this back up in the future.
