V6(Cidr)

IPv6 block

Implementations

impl Cidr

pub const IPV4_BITS: u8 = 32u8

Number of bits within ipv4 address

pub const IPV6_BITS: u8 = 128u8

Number of bits within ipv6 address

pub const fn new(addr: IpAddr, prefix: u8) -> Option<Self>

Constructs new CIDR verifying that prefix fits provided addrs

Returns None if prefix is greater than address length

pub const fn new_v4(addr: Ipv4Addr, prefix: u8) -> Option<Self>

Constructs new CIDR verifying that prefix fits provided addrs

Returns None if prefix is greater than address length

pub const fn new_v6(addr: Ipv6Addr, prefix: u8) -> Option<Self>

Constructs new CIDR verifying that prefix fits provided addrs

Returns None if prefix is greater than address length

pub const fn addr(&self) -> IpAddr

Returns address

pub const fn prefix(&self) -> u8

Returns prefix

pub const fn network_addr(&self) -> IpAddr

Computes network address from provided addr and prefix, which is lowest possible address within CIDR block

pub const fn broadcast_addr(&self) -> IpAddr

Computes network address from provided addr and prefix, which is highest possible address within CIDR block

pub const fn size(&self) -> u128

Returns maximum number of addresses within the block

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

Checks if a given addr is contained within self

pub const fn get(&self, idx: u128) -> Option<IpAddr>

Attempts to fetch address by idx within the block self

pub const fn get_unchecked(&self, idx: u128) -> IpAddr

Returns address corresponding idx without checking size according to the prefix

This is safe in a sense as it is only wrapping math operation, but it should be only used when you know need to iterate over possible addresses by pre-computing size

Trait Implementations

impl Clone for Cidr

fn clone(&self) -> Cidr

Returns a duplicate 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 Display for Cidr

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

Formats the value using the given formatter.

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.
