Struct Network 

pub struct Network { /* private fields */ }

An IP network with its host bits cleared, displayed as addr/prefix (e.g. 10.0.0.0/8, 2001:db8::/32).

Implementations

impl Network

pub fn new(addr: IpAddr, prefix: u8) -> Result<Self, Error>

Builds the network of length prefix containing addr.

IPv4-mapped IPv6 addresses (::ffff:a.b.c.d) are treated as IPv4, so a client reaching a dual-stack listener is matched against IPv4 networks: ::ffff:192.0.2.0/120 is 192.0.2.0/24. A mapped network shorter than /96 spans more than IPv4 and is refused.

pub fn enclosing(addr: IpAddr) -> impl Iterator<Item = Self>

Returns every network containing addr, from /0 to the host itself (/32 or /128).

pub fn host(addr: IpAddr) -> Self

The host network (/32 or /128) of addr.

Trait Implementations

impl Clone for Network

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Network

impl Debug for Network

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

impl Eq for Network

impl FromStr for Network

fn from_str(s: &str) -> Result<Self, Error>

Parses addr/prefix; a bare address is read as a host network.

type Err = Error

The associated error which can be returned from parsing.

impl Hash for Network

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Network

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

Equality operator ==.

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

Inequality operator !=.
