Tracking Issue for `const_sockaddr_setters`

[tgross35]

Feature gate: #![feature(const_sockaddr_setters)]

This is a tracking issue using the set_ip and set_port methods on SocketAddr types in const contexts.

Public API

// core::net

impl SocketAddr {
    pub const fn set_ip(&mut self, new_ip: IpAddr);
    pub const fn set_port(&mut self, new_port: u16);
}

impl SocketAddrV4 {
    pub const fn set_ip(&mut self, new_ip: Ipv4Addr);
    pub const fn set_port(&mut self, new_port: u16);
}

impl SocketAddrV6 {
    pub const fn set_ip(&mut self, new_ip: Ipv6Addr);
    pub const fn set_port(&mut self, new_port: u16);
    pub const fn set_flowinfo(&mut self, new_flowinfo: u32);
    pub const fn set_scope_id(&mut self, new_scope_id: u32);
}

@rust-lang/libs-api @rust-lang/wg-const-eval these are all fairly simple methods that have long been stable (since Rust 1.9), and I think are ready to be made const-stable.

// core::net

impl SocketAddr {
    pub const fn set_ip(&mut self, new_ip: IpAddr);
    pub const fn set_port(&mut self, new_port: u16);
}

impl SocketAddrV4 {
    pub const fn set_ip(&mut self, new_ip: Ipv4Addr);
    pub const fn set_port(&mut self, new_port: u16);
}

impl SocketAddrV6 {
    pub const fn set_ip(&mut self, new_ip: Ipv6Addr);
    pub const fn set_port(&mut self, new_port: u16);
    pub const fn set_flowinfo(&mut self, new_flowinfo: u32);
    pub const fn set_scope_id(&mut self, new_scope_id: u32);
}
