ip_network

IPv4 and IPv6 network structs.

Documentation Build Status Coverage Status Crates.io

Usage

Add this to your Cargo.toml:

[dependencies]
ip_network = "0.4"

this to your crate root (not necessary when your project is Rust 2018 edition):

extern crate ip_network;

and then you can use it like this:

use std::net::Ipv4Addr;
use ip_network::Ipv4Network;

let ip_network = Ipv4Network::new(Ipv4Addr::new(192, 168, 1, 0), 24)?;
assert_eq!(Ipv4Addr::new(192, 168, 1, 0), ip_network.network_address());
assert_eq!(24, ip_network.netmask());
assert_eq!(254, ip_network.hosts().len());
assert_eq!("192.168.1.0/24", ip_network.to_string());

Minimal required version of Rust compiler is:

  • 1.31 for version 0.3 and newer (because of 2018 edition),
  • 1.26 for version 0.2 (because of support u128 data type),
  • for older compiler you can use 0.1 version.

Optional features

When using this crate, you can choose to compile with these features:

Serde support

To enable serialization and deserialization by Serde framework, just add serde feature to package in your Cargo.toml:

[dependencies]
ip_network = { version = "0.4", features = ["serde"] }

Diesel support

To enable support for diesel CIDR type for PostgreSQL, just add diesel feature to package in your Cargo.toml:

[dependencies]
ip_network = { version = "0.4", features = ["diesel"] }

You can then use ip_network::diesel_support::PqCidrExtensionMethods trait for CIDR operators support.

Postgres support

To enable support for postgres crate CIDR type, just add postgres feature to package in your Cargo.toml:

[dependencies]
ip_network = { version = "0.4", features = ["postgres"] }
