This crate is meant as a replacement for an existing reimplementation of various "netaddr" libraries that other languages have.
There does exist another
netaddr crate, however the author of this crate did not respond when asked about maintainership status.
What it does
NetAddr arose out of a need to mask and subnet IP space in a manner identical to that which routers and network interfaces do.
Its utility may be most fully realized in the development of tooling for such purposes.
There are a few ways to use this library.
Perhaps most ergonomical of these is to use the
let net: NetAddr = "ff02::1/128".parse().unwrap(); let net: Netv4Addr = "203.0.113.19/29".parse().unwrap();
(More options will be added eventually.)
This crate aims to be as simple and straightforward as possible.
We accomplish this by mirroring the structure of the
std::net::Ip.*Addr data structures.
Most of the operations on
NetAddr structs are implemented through the use of traits which are implemented both on the main structures and on the enum that bridges them.
These are also implemented, where appropriate, for standard library structures.
This crate has no dependencies, and will not accept any unless required for
The only part of this crate that uses
std is the part that bridges with
std::net::IpAddr, so a potential contribution would be to generalize
std::net::IpAddr in a
This codebase is still not feature-complete. Check out the issue tracker if you want to contribute, and don't hesistate to ask for something in an Issue. That said, the business logic is tested and should work. We will release version 1.0 when the GitHub milestone has been fully resolved.
