Struct TimeWindow 

pub struct TimeWindow { /* private fields */ }

A time-based window with start and end timestamps.

This is the fundamental window type for time-based windowing strategies.

Implementations

impl TimeWindow

pub fn new(start: DateTime<Utc>, end: DateTime<Utc>) -> Self

Creates a new time window with the given start and end.

pub fn start(&self) -> DateTime<Utc>

Returns the start time of the window.

pub fn end(&self) -> DateTime<Utc>

Returns the end time of the window.

pub fn duration(&self) -> ChronoDuration

Returns the duration of the window.

pub fn max_timestamp(&self) -> DateTime<Utc>

Returns the maximum timestamp for elements in this window.

pub fn contains(&self, timestamp: DateTime<Utc>) -> bool

Returns true if the given timestamp falls within this window.

pub fn intersects(&self, other: &TimeWindow) -> bool

Returns true if this window intersects with another.

pub fn merge(&self, other: &TimeWindow) -> Option<TimeWindow>

Merges this window with another overlapping window.

Trait Implementations

impl Clone for TimeWindow

fn clone(&self) -> TimeWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeWindow

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

Formats the value using the given formatter.

impl Display for TimeWindow

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

Formats the value using the given formatter.

impl Hash for TimeWindow

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 TimeWindow

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 TimeWindow

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 TimeWindow

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 Window for TimeWindow

fn end_time(&self) -> Option<DateTime<Utc>>

Returns the end time of the window, if applicable. Returns None for windows without a defined end (e.g., global windows).

fn start_time(&self) -> Option<DateTime<Utc>>

Returns the start time of the window, if applicable.

fn contains(&self, timestamp: DateTime<Utc>) -> bool

Returns true if this window contains the given timestamp.

impl WindowTrigger<TimeWindow> for EventTimeTrigger

fn on_element( &mut self, _timestamp: DateTime<Utc>, _window: &TimeWindow, ) -> TriggerResult

Called when an element is added to a window.

fn on_processing_time( &mut self, _time: DateTime<Utc>, _window: &TimeWindow, ) -> TriggerResult

Called when processing time advances.

fn on_event_time( &mut self, watermark: DateTime<Utc>, window: &TimeWindow, ) -> TriggerResult

Called when the watermark (event time) advances.

fn clear(&mut self, _window: &TimeWindow)

Called when the trigger is cleared.

fn clone_trigger(&self) -> Box<dyn WindowTrigger<TimeWindow>>

Creates a clone of this trigger.

impl WindowTrigger<TimeWindow> for ProcessingTimeTrigger

fn on_element( &mut self, _timestamp: DateTime<Utc>, _window: &TimeWindow, ) -> TriggerResult

fn on_processing_time( &mut self, time: DateTime<Utc>, window: &TimeWindow, ) -> TriggerResult

Called when processing time advances.

fn on_event_time( &mut self, _watermark: DateTime<Utc>, _window: &TimeWindow, ) -> TriggerResult

Called when the watermark (event time) advances.

fn clear(&mut self, window: &TimeWindow)

Called when the trigger is cleared.

fn clone_trigger(&self) -> Box<dyn WindowTrigger<TimeWindow>>

Creates a clone of this trigger.
