Struct NumericAggregationUdf 

pub struct NumericAggregationUdf { /* private fields */ }

A user-defined numeric aggregation. The aggregation builder controls grouping/windowing. Supported Rust entrypoints accept grouped value vectors, optionally with leading sample timestamps, and return either one numeric value or timestamped numeric point(s), e.g. fn rms(values: Vec<f64>) -> f64, fn energy(timestamp_ns: Vec<i64>, values: Vec<f64>) -> f64, fn first(timestamp_ns: Vec<i64>, values: Vec<f64>) -> (i64, f64), or fn passthrough(timestamp_ns: Vec<i64>, values: Vec<f64>) -> Vec<(i64, f64)>.

Implementations

impl NumericAggregationUdf

pub fn builder() -> Builder<SourceStage>

Returns a new builder.

Constructs a new instance of the type.

pub fn source(&self) -> &UdfSource

Trait Implementations

impl Clone for NumericAggregationUdf

fn clone(&self) -> NumericAggregationUdf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericAggregationUdf

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NumericAggregationUdf

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<NumericAggregationUdf> for Builder<Complete>

fn from(v: NumericAggregationUdf) -> Self

Converts to this type from the input type.

impl Hash for NumericAggregationUdf

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 NumericAggregationUdf

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

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

fn partial_cmp(&self, other: &NumericAggregationUdf) -> 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 NumericAggregationUdf

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
