 1 | # local_ipaddress
 2 | 
 3 | Get your local ip address in Rust, using `UdpSocket` to get local ip address(not `network interface` or `ifconfig`), and won't `panic`.
 4 | 
 5 | API Docs: [https://docs.rs/local_ipaddress](https://docs.rs/local_ipaddress)
 6 | 
 7 | ### Usage
 8 | 
 9 | Add this to your Cargo.toml:
10 | 
11 | 
12 | ```
13 | [dependencies]
14 | local_ipaddress = "0.1.3"
15 | ```
16 | 
17 | ### Getting Started
18 | 
19 | ```rust
20 | use local_ipaddress;
21 | 
22 | fn main() {
23 |     println!("{}", local_ipaddress::get().unwrap());
24 | }
25 | ```
26 | 
27 | It works fine with both `Windows` and `Linux`.
