Struct Ipv4Cidr

pub struct Ipv4Cidr { /* private fields */ }

A specification of an IPv4 CIDR block, containing an address and a variable-length subnet masking prefix length.

Implementations

impl Cidr

pub const fn new(address: Address, prefix_len: u8) -> Cidr

Create an IPv4 CIDR block from the given address and prefix length.

Panics

This function panics if the prefix length is larger than 32.

pub fn from_netmask(addr: Address, netmask: Address) -> Result<Cidr>

Create an IPv4 CIDR block from the given address and network mask.

pub const fn address(&self) -> Address

Return the address of this IPv4 CIDR block.

pub const fn prefix_len(&self) -> u8

Return the prefix length of this IPv4 CIDR block.

pub const fn netmask(&self) -> Address

Return the network mask of this IPv4 CIDR.

pub fn broadcast(&self) -> Option<Address>

Return the broadcast address of this IPv4 CIDR.

pub const fn network(&self) -> Cidr

Return the network block of this IPv4 CIDR.

pub fn contains_addr(&self, addr: &Address) -> bool

Query whether the subnetwork described by this IPv4 CIDR block contains the given address.

pub fn contains_subnet(&self, subnet: &Cidr) -> bool

Query whether the subnetwork described by this IPv4 CIDR block contains the subnetwork described by the given IPv4 CIDR block.

Trait Implementations

impl Clone for Cidr

fn clone(&self) -> Cidr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cidr

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

Formats the value using the given formatter.

impl Default for Cidr

fn default() -> Cidr

Returns the “default value” for a type.

impl Display for Cidr

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

Formats the value using the given formatter.

impl From<Cidr> for Cidr

fn from(addr: Ipv4Cidr) -> Self

Converts to this type from the input type.

impl FromStr for Ipv4Cidr

fn from_str(s: &str) -> Result<Ipv4Cidr, ()>

Parse a string representation of an IPv4 CIDR.

type Err = ()

The associated error which can be returned from parsing.

impl Hash for Cidr

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 Ord for Cidr

fn cmp(&self, other: &Cidr) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Cidr

fn eq(&self, other: &Cidr) -> 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.

impl PartialOrd for Cidr

fn partial_cmp(&self, other: &Cidr) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
