Struct LineageEvent 

pub struct LineageEvent {
    pub timestamp: LamportTimestamp,
    pub event_type: LineageEventType,
    pub run_id: String,
    pub context: Option<String>,
}

A single event in the causal lineage

Fields

timestamp: LamportTimestamp

Lamport timestamp for causal ordering

event_type: LineageEventType

Type of event

run_id: String

Associated run ID

context: Option<String>

Optional additional context

Implementations

impl LineageEvent

pub fn new( timestamp: LamportTimestamp, event_type: LineageEventType, run_id: &str, ) -> Self

Create a new lineage event

pub fn with_context(self, context: impl Into<String>) -> Self

Add context to the event

Trait Implementations

impl Clone for LineageEvent

fn clone(&self) -> LineageEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineageEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LineageEvent

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LineageEvent

impl Ord for LineageEvent

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 LineageEvent

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

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 LineageEvent

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
