Struct Ipv4Mask

#[repr(align(4))]
pub struct Ipv4Mask { /* private fields */ }

A 4-byte type representing a subnet mask. This type can only be a valid subnet mask.

Implementations

impl Ipv4Mask

pub const fn new(len: u8) -> Self

Returns a mask with the specified length.

Panics

Will panic if provided length is > 32

pub fn from_bytes(bytes: [u8; 4]) -> Option<Self>

Constructs a subnet mask from the provided bytes, if they represent a valid mask.

pub fn from_u32(x: u32) -> Option<Self>

Constructs a subnet mask from the provided u32, if it represents a valid mask.

pub const fn octets(self) -> [u8; 4]

Returns the subnet mask as an array of bytes.

pub const fn as_u32(self) -> u32

Returns this mask in u32 representation

pub const fn len(self) -> u8

Returns the length of the mask. That is, the number of 1 bits in this mask.

Trait Implementations

impl Clone for Ipv4Mask

fn clone(&self) -> Ipv4Mask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ipv4Mask

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

Formats the value using the given formatter.

impl Display for Ipv4Mask

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

Formats the value using the given formatter.

impl FromStr for Ipv4Mask

type Err = InvalidIpv4Mask

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, InvalidIpv4Mask>

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

impl Hash for Ipv4Mask

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 IpBitwiseExt<Ipv4Mask> for Ipv4Addr

type Output = Ipv4Addr

The output type of this operation.

fn bitand(self, rhs: Ipv4Mask) -> Self

Bitwise And operation.

fn bitor(self, rhs: Ipv4Mask) -> Self

Bitwise Or operation.

fn bitxor(self, rhs: Ipv4Mask) -> Self

Bitwise Xor operation.

impl Not for Ipv4Mask

type Output = [u8; 4]

The resulting type after applying the ! operator.

fn not(self) -> [u8; 4]

Performs the unary ! operation.

impl PartialEq for Ipv4Mask

fn eq(&self, other: &Ipv4Mask) -> 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.
