Struct Ipv4Prefix 

pub struct Ipv4Prefix {
    pub addr: Ipv4Addr,
    pub len: u8,
}

An IPv4 prefix (network address + prefix length).

Stored in canonical form: host bits are always zero.

Fields

addr: Ipv4Addr

Network address (host bits zeroed).

len: u8

Prefix length in bits (0–32).

Implementations

impl Ipv4Prefix

pub fn new(addr: Ipv4Addr, len: u8) -> Self

Create a new prefix, masking off host bits.

Prefix length is clamped to 32 (values above 32 are silently reduced). This is intentional: wire decoders validate prefix lengths before construction, and clamping is safer than panicking for internal callers that may compute lengths arithmetically.

Trait Implementations

impl Clone for Ipv4Prefix

fn clone(&self) -> Ipv4Prefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ipv4Prefix

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

Formats the value using the given formatter.

impl Display for Ipv4Prefix

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

Formats the value using the given formatter.

impl Hash for Ipv4Prefix

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 Ipv4Prefix

fn cmp(&self, other: &Ipv4Prefix) -> 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 Ipv4Prefix

fn eq(&self, other: &Ipv4Prefix) -> 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 Ipv4Prefix

fn partial_cmp(&self, other: &Ipv4Prefix) -> 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.
