Enum cidr::AnyIpCidr

pub enum AnyIpCidr {
    Any,
    V4(Ipv4Cidr),
    V6(Ipv6Cidr),
}

Represents either an IPv4 or an IPv6 network or "any".

Allows for a bit string representation which treats "any" as the empty string, IPv4 as starting with false and IPv6 as starting with true. After the first bit the normal represenation for the picked address-family follows.

Setting the first bit always truncates the bit string to length 1.

The Cidr trait itself cannot be implemented because Any has no address family, but there is a very similar interface implemented directly.

Variants

Any

"any" network containing all IPv4 and IPv6 addresses

V4(Ipv4Cidr)

IPv4 network

V6(Ipv6Cidr)

IPv6 network

Methods

impl AnyIpCidr

fn is_any(&self) -> bool

Whether representing any address

fn is_ipv4(&self) -> bool

Whether representing an IPv4 network

fn is_ipv6(&self) -> bool

Whether representing an IPv6 network

impl AnyIpCidr

fn new(addr: IpAddr, len: u8) -> Result<Self, NetworkParseError>

Create new network from address and prefix length. If the network length exceeds the address length or the address is not the first address in the network ("host part not zero") an error is returned.

fn new_host(addr: IpAddr) -> Self

Create a network containing a single address (network length = address length).

fn first_address(&self) -> Option<IpAddr>

first address in the network as plain address

returns None for Any

fn first(&self) -> Option<IpInet>

first address in the network

returns None for Any

fn last_address(&self) -> Option<IpAddr>

last address in the network as plain address

returns None for Any

fn last(&self) -> Option<IpInet>

last address in the network

returns None for Any

fn network_length(&self) -> Option<u8>

length in bits of the shared prefix of the contained addresses

returns None for Any

fn family(&self) -> Option<Family>

IP family of the contained address (Ipv4 or Ipv6).

returns None for Any

fn mask(&self) -> Option<IpAddr>

network mask: an pseudo address which has the first network length bits set to 1 and the remaining to 0.

returns None for Any

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

check whether an address is contained in the network
