A crate to return the name and maximum transmission unit (MTU) of the local network interface
towards a given destination `SocketAddr`, optionally from a given local `SocketAddr`.
# Usage
This crate exports a single function `interface_and_mtu` that returns the name and
[maximum transmission unit (MTU)](https://en.wikipedia.org/wiki/Maximum_transmission_unit)
of the outgoing network interface towards a remote destination identified by an `IpAddr`.
# Example
```
# use std::net::{IpAddr, Ipv4Addr};
let destination = IpAddr::V4(Ipv4Addr::LOCALHOST);
let (name, mtu): (String, usize) = mtu::interface_and_mtu(destination).unwrap();
println!("MTU towards {destination} is {mtu} on {name}");
```
# Supported Platforms
* Linux
* macOS
* Windows
* FreeBSD
* NetBSD
* OpenBSD
* Solaris
# Notes
The returned MTU may exceed the maximum IP packet size of 65,535 bytes on some platforms for
some remote destinations. (For example, loopback destinations on Windows.)
The returned interface name is obtained from the operating system.
