Function netaddr2::mask

pub fn mask<T, U>(addr: &T, mask: &T) -> T where
    U: From<T>,
    U: BitAnd<U, Output = U>,
    T: From<U>,
    T: Copy, 

Mask the given referenced addr with the given mask, returning a new IpAddr.

Both addr and mask must be of the same enum variant for the operation to succeed.

Because this method is a generic, you will need to be sure to use type annotations to specify which types it runs on. For Ipv4Addr masking, you should use ::<Ipv4Addr, u32> and for Ipv6Addr masking, the best choice is ::<Ipv6Addr, u128>. The Rust compiler will complain if you try to do this with incompatible types.

Examples

let addr = Ipv4Addr::new(127, 0, 0, 1);
let mask = Ipv4Addr::new(255, 0, 0, 0);
assert_eq!(netaddr2::mask::<Ipv4Addr, u32>(&addr, &mask), Ipv4Addr::new(127, 0, 0, 0));
