Struct SequenceNumber 

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

Implementations

impl SequenceNumber

pub const UNSET: Self

Sentinel: sequence not set.

pub const ALL_DATA: Self

Sentinel: request all data (v4).

pub const V3_MAX: u64 = 0xFF_FFFF

Maximum sequence value for v3 (6 hex digits).

pub fn new(value: u64) -> Self

pub fn value(self) -> u64

pub fn is_special(self) -> bool

Returns true if this is a special sentinel value (UNSET or ALL_DATA).

pub fn from_v3_hex(hex: &str) -> Result<Self>

Parse v3 hex representation (6 uppercase hex digits, e.g. “00001A”).

pub fn to_v3_hex(self) -> String

Serialize to v3 hex (6 uppercase hex digits).

pub fn from_v4_decimal(s: &str) -> Result<Self>

Parse v4 decimal string (e.g. “26”).

pub fn to_v4_decimal(self) -> String

Serialize to v4 decimal string.

pub fn from_v4_le_bytes(bytes: [u8; 8]) -> Self

Parse from v4 little-endian bytes (frame header).

pub fn to_v4_le_bytes(self) -> [u8; 8]

Serialize to v4 little-endian bytes (frame header).

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 Display for SequenceNumber

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

Formats the value using the given formatter.

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: &Self) -> 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: &Self) -> 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.
