# default-net
Get default network interface information
Get default network information
`default-net` provides a cross-platform API for network interface and gateway.
## Supported platform
- Linux
- macOS(OS X)
- Windows
## Usage
Add `default-net` to your dependencies
```toml:Cargo.toml
[dependencies]
default-net = "0.1.0"
```
## Example
```rust
use default_net;
fn main(){
if let Some(default_interface) = default_net::get_default_interface(){
println!("Index {}", default_interface.index);
println!("Name {}", default_interface.name);
println!("MAC {:?}", default_interface.mac);
println!("IPv4 {:?}", default_interface.ipv4);
println!("IPv6 {:?}", default_interface.ipv6);
println!("Gateway IP {:?}", default_interface.gateway.ip);
println!("Gateway MAC {:?}", default_interface.gateway.mac);
}else{
println!("Failed to get default interface info");
}
}
```
For more details, see examples or doc.
