Build Status: 
A set of macros for creating networking types from a string literal.
Each of the macros will parse using the FromStr implementation for
the appropriate type. The generated code will use a const constructor
for the type, if one exists.
use std::net::Ipv4Addr;
use const_addrs::ip4;
let a = ip4!("192.168.1.1");
let b = Ipv4Addr::new(192,168,1,1);
assert_eq!(a, b);And turns invalid strings into compile-time errors:
error: invalid IPv4 address syntax
--> bad.rs:10:18
|
10 | let a = ip4!("192.1681.1");
| ^^^^^^^^^^^^
There are macros for:
| Type | macro |
|---|---|
std::net::IpAddr |
ip! |
std::net::Ipv4Addr |
ip4! |
std::net::Ipv6Addr |
ip6! |
std::net::SocketAddr |
sock! |
std::net::SocketAddrV4 |
sock4! |
std::net::SocketAddrV6 |
sock6! |
ipnet::IpNet |
ipnet! |
ipnet::Ipv4Net |
ipnet4! |
ipnet::Ipv6Net |
ipnet6! |
ipnetwork::IpNetwork |
net! |
ipnetwork::Ipv4Network |
net4! |
ipnetwork::Ipv6Network |
net6! |
macaddr::MacAddr |
mac! |
macaddr::MacAddr6 |
mac6! |
macaddr::MacAddr8 |
mac8! |
Note: using ipnet::* types requires you to have the
ipnet crate in your depdencies. These
types can be enabled with the ipnet feature.
Note: using ipnetwork::* types requires you to have the
ipnetwork crate in your depdencies. These
types can be enabled with the ipnetwork feature.
Note: using macaddr::* requires the
macaddr crate in your depdencies. These
types can be enabled with the mac feature.
When possible the expanded macro uses const constructors, allowing for simple
string representations of network types without the cost of runtime parsing.
