Struct SequenceNumber 

pub struct SequenceNumber(pub u32);

Sequence Number - 24-bit message sequence number (stored as u32).

Per 3GPP TS 29.244 Section 5.1, the sequence number is a 24-bit field used to match request and response messages. Valid range: 0 to 0x00FFFFFF.

Examples

use rs_pfcp::types::SequenceNumber;

// Create with masking to 24 bits
let seq = SequenceNumber::new(0x123456);
assert_eq!(*seq, 0x123456);

// Values larger than 24 bits are masked
let seq = SequenceNumber::new(0xFF123456);
assert_eq!(*seq, 0x123456);

// Increment with wrap-around
let seq = SequenceNumber::new(SequenceNumber::MAX);
let next = seq.next();
assert_eq!(*next, 0);

Tuple Fields

0: u32

Implementations

impl SequenceNumber

pub const MAX: u32 = 0x00FFFFFF

Maximum value for a 24-bit sequence number.

pub const fn new(value: u32) -> Self

Creates a new sequence number, masking to 24 bits.

pub const fn value(&self) -> u32

Returns the inner u32 value.

pub const fn next(&self) -> Self

Returns the next sequence number with wrap-around at MAX.

Examples

use rs_pfcp::types::SequenceNumber;

let seq = SequenceNumber::new(100);
assert_eq!(*seq.next(), 101);

let max_seq = SequenceNumber::new(SequenceNumber::MAX);
assert_eq!(*max_seq.next(), 0);

pub const fn is_valid(&self) -> bool

Checks if this sequence number is within a valid 24-bit range.

Always returns true since the constructor masks to 24 bits.

Trait Implementations

impl Clone for SequenceNumber

fn clone(&self) -> SequenceNumber

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SequenceNumber

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

Formats the value using the given formatter.

impl Default for SequenceNumber

fn default() -> SequenceNumber

Returns the “default value” for a type.

impl Deref for SequenceNumber

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for SequenceNumber

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

Formats the value using the given formatter.

impl From<SequenceNumber> for u32

fn from(seq: SequenceNumber) -> Self

Converts to this type from the input type.

impl From<u32> for SequenceNumber

fn from(value: u32) -> Self

Converts to this type from the input type.

impl Hash for SequenceNumber

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 SequenceNumber

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

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

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