Methods

impl Ipv4Mask

pub fn prefixlen(&self) -> u32

assert_eq!(Ipv4Mask::try_from(0xffff_ffff).unwrap().prefixlen(), 32);
assert_eq!(Ipv4Mask::try_from(0xfff8_0000).unwrap().prefixlen(), 13);

pub fn from_prefixlen(prefixlen: u8) -> Result<Self, InvalidMask>

Create an Ipv4Mask from a prefix length.

assert_eq!(Ipv4Mask::from_prefixlen(0).unwrap(), Ipv4Mask::try_from(0).unwrap());
assert_eq!(Ipv4Mask::from_prefixlen(32).unwrap(), Ipv4Mask::try_from(0xffff_ffff).unwrap());

pub fn to_string(&self) -> String

Return a human readable representation of the IPv4 mask.

let mask = Ipv4Mask::try_from(0xfff8_0000).unwrap();
assert_eq!(mask.to_string(), "255.248.0.0".to_string());
