Struct CountWindow 

pub struct CountWindow { /* private fields */ }

A count-based window that holds a fixed number of elements.

Implementations

impl CountWindow

pub fn new(id: u64, max_count: usize) -> Self

Creates a new count window with the given ID and max count.

pub fn id(&self) -> u64

Returns the window ID.

pub fn max_count(&self) -> usize

Returns the maximum count for this window.

Trait Implementations

impl Clone for CountWindow

fn clone(&self) -> CountWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CountWindow

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

Formats the value using the given formatter.

impl Display for CountWindow

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

Formats the value using the given formatter.

impl Hash for CountWindow

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 PartialEq for CountWindow

fn eq(&self, other: &CountWindow) -> 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 WindowTrigger<CountWindow> for CountTrigger

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

Called when an element is added to a window.

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

Called when processing time advances.

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

Called when the watermark (event time) advances.

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

Called when the trigger is cleared.

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

Creates a clone of this trigger.
