Struct iptrie::Ipv4Prefix

pub struct Ipv4Prefix { /* private fields */ }

An Ipv4 prefix similar to Ipv4Net but with trailing bits guaranteed to equal 0

Implementations

impl Ipv4Prefix

pub fn new(addr: Ipv4Addr, len: u8) -> Result<Self, IpPrefixError>

Build a new prefix.

All the bits greater than the prefix length are set to `0``. If the specified length is greater than the maximum allowed, an error is returned.

Example

use std::net::{Ipv4Addr, Ipv6Addr};
    use ipnet::PrefixLenError;
    let ipv4 = "1.2.3.4".parse::<Ipv4Addr>().unwrap();
    let ipv6 = "1:2:3:4::".parse::<Ipv6Addr>().unwrap();

    assert!( Ipv4Prefix::new(ipv4, 12).is_ok());

    assert_eq!( Ipv4Prefix::new(ipv4, 64), Err(IpPrefixError::PrefixLenError));

The inner slot with all the masked bits set to 0.

fn len(&self) -> u8

Length of the prefix.

const MAX_LEN: u8 = 32u8

The maximum allowed length for this prefix

type Addr = Ipv4Addr

The underlying ip address (usually Ipv4Addr or Ipv6Addr)

fn network(&self) -> Self::Addr

impl PartialEq<Ipv4Prefix> for Ipv4Prefix

fn eq(&self, other: &Ipv4Prefix) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
