Struct OrderingKey 

pub struct OrderingKey {
    pub epoch_id: EpochId,
    pub workspace_id: WorkspaceId,
    pub seq: u64,
    pub wall_clock_ms: u64,
}

Composite ordering key for causal ordering of operations.

Ordering is determined by the authoritative triple (epoch_id, workspace_id, seq). The wall_clock_ms field is informational only and excluded from ordering.

Fields

epoch_id: EpochId

The epoch this operation belongs to.

workspace_id: WorkspaceId

The workspace that produced this operation.

seq: u64

Monotonically increasing sequence number within a workspace.

wall_clock_ms: u64

Wall-clock milliseconds since Unix epoch (informational only). Clamped: never goes backward within a workspace.

Implementations

impl OrderingKey

pub const fn new( epoch_id: EpochId, workspace_id: WorkspaceId, seq: u64, wall_clock_ms: u64, ) -> Self

Create a new ordering key with explicit values.

Trait Implementations

impl Clone for OrderingKey

fn clone(&self) -> OrderingKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderingKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OrderingKey

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for OrderingKey

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

Formats the value using the given formatter.

impl Ord for OrderingKey

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 OrderingKey

fn eq(&self, other: &Self) -> 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 OrderingKey

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.

impl Serialize for OrderingKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
