Struct Rank 

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

A rank value for ordering register operations

Encodes both a process identifier and a sequence number into a single u64. The high 32 bits hold the sequence number, and the low 32 bits hold the process ID. This ensures that ranks from the same process are ordered by sequence, and ties between different processes are broken by process ID.

Encoding

|--- sequence (32 bits) ---|--- process_id (32 bits) ---|

Implementations

impl Rank

pub const ZERO: Rank

The zero rank, representing the bottom/uninitialized state

pub fn new(process_id: u32, sequence: u32) -> Self

Create a new rank from a process ID and sequence number

The sequence occupies the high 32 bits and the process ID the low 32 bits, so ranks are ordered primarily by sequence, then by process ID.

pub fn process_id(&self) -> u32

Returns the process ID component of this rank

pub fn sequence(&self) -> u32

Returns the sequence number component of this rank

pub fn as_u64(&self) -> u64

Returns the raw u64 representation

Trait Implementations

impl Clone for Rank

fn clone(&self) -> Rank

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rank

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

Formats the value using the given formatter.

impl Default for Rank

fn default() -> Rank

Returns the “default value” for a type.

impl Display for Rank

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

Formats the value using the given formatter.

impl From<u64> for Rank

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Hash for Rank

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 Rank

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

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

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