Struct Watermark 

pub struct Watermark {
    pub timestamp: i64,
}

Represents a watermark timestamp

Watermarks indicate that all events with timestamps less than or equal to the watermark have been processed. This allows the system to trigger time-based operations and detect late-arriving events.

Fields

timestamp: i64

The watermark timestamp in milliseconds since epoch

Implementations

impl Watermark

pub fn new(timestamp: i64) -> Self

Creates a new watermark with the given timestamp

pub fn from_datetime(dt: DateTime<Utc>) -> Self

Creates a watermark from a DateTime

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

Converts the watermark to a DateTime

pub fn min() -> Self

Returns the minimum possible watermark (beginning of time)

pub fn max() -> Self

Returns the maximum possible watermark (end of time)

pub fn is_before(&self, timestamp: i64) -> bool

Checks if this watermark is before the given timestamp

pub fn is_after(&self, timestamp: i64) -> bool

Checks if this watermark is after the given timestamp

pub fn is_min(&self) -> bool

Returns true if this is the minimum watermark

pub fn is_max(&self) -> bool

Returns true if this is the maximum 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 Default for Watermark

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Watermark

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display 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.

impl Serialize for Watermark

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
