Struct MaskedIpv4

pub struct MaskedIpv4 {
    pub ip: Ipv4Addr,
    pub mask: Ipv4Mask,
}

An 8-byte type representing an IPv4 address and subnet mask pair. The IP may be any ip within the represented network, and the mask may be any valid subnet mask.

Fields

ip: Ipv4Addr

The IP address

mask: Ipv4Mask

The subnet mask

Implementations

impl MaskedIpv4

pub const fn new(ip: Ipv4Addr, mask: Ipv4Mask) -> Self

Constructs a MaskedIpv4 from the provided ip and mask.

pub const fn cidr(ip: Ipv4Addr, mask_len: u8) -> Self

Constructs a MaskedIpv4 from the provided ip and mask length.

Panics

Will panic if provided length > 32

pub fn from_cidr_str(s: &str) -> Option<Self>

Constructs a new MaskedIpv4 from the provided CIDR string.

pub fn from_network_str(s: &str) -> Option<Self>

Constructs a new MaskedIpv4 from the provided IP and subnet mask. There must be exactly one space between the IP and mask.

pub fn to_cidr_string(&self) -> String

Returns a String with the IP and mask in CIDR format. Shortcut for format!("{:#}", self)

pub fn to_network_string(&self) -> String

Returns a String with the IP and mask in dotted decimal format. Shortcut for format!("{}", self)

pub fn network_address(&self) -> Ipv4Addr

Returns the network adderss by setting all host bits to 0.

pub fn network(&self) -> MaskedIpv4

Constructs a new MaskedIpv4 using the network address and mask of this MaskedIpv4.

pub fn is_network_address(&self) -> bool

Returns true if all host bits in the IP are 0. Always returns false if the mask length is 31 or 32.

pub fn broadcast_address(&self) -> Ipv4Addr

Returns the broadcast address by setting all host bits to 1.

pub fn is_broadcast_address(&self) -> bool

Returns true if all host bits in the IP are 1. Always returns false if the mask length is 31 or 32.

pub fn network_bits(&self) -> u8

Returns the number of network bits. That is, the length of the mask.

pub fn host_bits(&self) -> u8

Returns the number of host bits. That is, the number of 0 bits in the mask.

pub fn host_count(&self) -> usize

Returns the number of host addresses in the network.

Panics

Will panic if usize is not large enough to hold the host count.

pub fn host_count_u64(&self) -> u64

Returns the number of host addresses in the network as u64. Unlike host_count, this will never panic.

pub fn network_count(&self, len: u8) -> usize

Returns the number of networks of the provided mask length will fit in this network.

Panics

Will panic if the provided length is > 32, or if the number of networks does not fit in usize

pub fn network_count_u64(&self, len: u8) -> u64

Returns the number of networks of the provided mask length will fit in this network as u64. Unlike network_count, this will not panic due to overflow. May still panic if the provided length is too long.

Panics

Will panic if the provided length is > 32

pub fn contains(&self, ip: Ipv4Addr) -> bool

Returns true if this network contains the provided IP address, even if the provided IP is the network or broadcast address.

Trait Implementations

impl Clone for MaskedIpv4

fn clone(&self) -> MaskedIpv4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MaskedIpv4

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

Formats the value using the given formatter.

impl Display for MaskedIpv4

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

Formats the value using the given formatter.

impl FromStr for MaskedIpv4

type Err = InvalidMaskedIpv4

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, InvalidMaskedIpv4>

Parses a string s to return a value of this type.

impl Hash for MaskedIpv4

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 MaskedIpv4

fn eq(&self, other: &MaskedIpv4) -> 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.
