pub struct Watermark {
    pub timestamp: u64,
}

Watermark representing event-time progress

Fields

timestamp: u64

Timestamp in milliseconds since UNIX epoch

Implementations

impl Watermark

pub fn new(timestamp: u64) -> Self

Create a new watermark with the given timestamp

pub fn from_system_time(time: SystemTime) -> Self

Create a watermark from system time

pub fn now() -> Self

Get current time watermark

pub fn is_before(&self, other: &Watermark) -> bool

Check if this watermark is before another

pub fn is_late(&self, event_time: u64) -> bool

Check if an event is late according to this watermark

Trait Implementations

impl Clone for Watermark

fn clone(&self) -> Watermark

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Watermark

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

Formats the value using the given formatter.

impl Ord for Watermark

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

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

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