Rust htons and ntohs

rust

Solution

These are now in `std::sys_common::net`, but `std::sys_common` is private. But their implementation in `src/libstd/sys/common/net.rs` is very simple:

pub fn htons(u: u16) -> u16 {
    u.to_be()
}
pub fn ntohs(u: u16) -> u16 {
    Int::from_be(u)
}

Problem

I have a program that has been relying on `native::io::net::{htons, ntohs}` but now errors on `Could not find 'io' in 'packet::native'`. The change seems to have happened some time in the last week Searching doesn't yield much info about the change and a search for `htons` or `ntohs` in the docs doesn't yield any useful information. What is the (new?) standard way to perform `htons` or `ntohs` in Rust? An obvious solution would be to write my own but one would expect that it would be in the standard library.
