Enum IpNet 

pub enum IpNet {
    V4 {
        addr: Ipv4Addr,
        prefix_len: u8,
    },
    V6 {
        addr: Ipv6Addr,
        prefix_len: u8,
    },
}

An IP network in CIDR notation, or a single host address (/32 or /128).

IPv4-mapped IPv6 addresses are normalised to IPv4 at parse time so that ::ffff:10.0.0.0/8 and 10.0.0.0/8 behave identically.

Variants

V4

Fields

addr: Ipv4Addr

prefix_len: u8

V6

Fields

addr: Ipv6Addr

prefix_len: u8

Implementations

impl IpNet

pub fn parse(s: &str) -> Result<Self, FilterError>

Parse an address or CIDR prefix string.

Errors

Returns FilterError::InvalidIp if the string cannot be parsed.

pub fn contains(&self, ip: IpAddr) -> bool

Return true if ip falls within this network.

An IPv4 network and an IPv6 network never overlap. The ip argument is normalised before comparison so that IPv4-mapped addresses match their IPv4 equivalents.

Trait Implementations

impl Clone for IpNet

fn clone(&self) -> IpNet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for IpNet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for IpNet

impl PartialEq for IpNet

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

Tests for self and other values to be equal, and is used by ==.

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

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