Struct FragmentOffset

pub struct FragmentOffset(/* private fields */);

An IP fragment offset.

Represents a fragment offset found in an IP header. The offset is expressed in units of 8 octets and must be smaller than 1 << 13.

This is valid for both IPv4 (RFC 791 Section 3.1) and IPv6 (RFC 8200 Section 4.5) headers.

Implementations

impl FragmentOffset

pub const ZERO: FragmentOffset = _

The zero fragment offset.

pub const fn new(offset: u16) -> Option<Self>

Creates a new offset from a raw u16 value.

Returns None if offset is not smaller than 1 << 13.

pub const fn new_with_bytes(offset_bytes: u16) -> Option<Self>

Creates a new offset from a raw bytes value.

Returns None if offset_bytes is not a multiple of 8.

pub const fn into_raw(self) -> u16

Consumes self returning the raw offset value in 8-octets multiples.

pub fn into_bytes(self) -> u16

Consumes self returning the total number of bytes represented by this offset.

Equal to 8 times the raw offset value.

Trait Implementations

impl Clone for FragmentOffset

fn clone(&self) -> FragmentOffset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FragmentOffset

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

Formats the value using the given formatter.

impl Hash for FragmentOffset

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 FragmentOffset

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

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

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