Struct ValueDifferenceSeries 

pub struct ValueDifferenceSeries { /* private fields */ }

Calculates the first discrete difference of the input series. For each point, computes the difference between the current value and the previous value (current - previous). The first point in the input series is omitted from the output since it has no previous point to compare against.

This is equivalent to pandas DataFrame.diff() with period=1. Useful for analyzing changes between consecutive data points in time series data, such as detecting value increases or decreases.

Example: For input values [1.0, 1.0, 2.0, 2.5, 1.8], the output would be [0.0, 1.0, 0.5, -0.7] at the corresponding timestamps (the first timestamp is omitted).

Implementations

impl ValueDifferenceSeries

pub fn builder() -> Builder<InputStage>

Returns a new builder.

impl ValueDifferenceSeries

pub fn new(input: NumericSeries) -> Self

Constructs a new instance of the type.

pub fn input(&self) -> &NumericSeries

pub fn negative_values_configuration( &self, ) -> Option<&NegativeValueConfiguration>

Defines the strategy for handling negative output values. Defaults to allowNegativeValues if not specified.

Trait Implementations

impl Clone for ValueDifferenceSeries

fn clone(&self) -> ValueDifferenceSeries

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueDifferenceSeries

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueDifferenceSeries

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ValueDifferenceSeries> for Builder<Complete>

fn from(v: ValueDifferenceSeries) -> Self

Converts to this type from the input type.

impl Hash for ValueDifferenceSeries

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 ValueDifferenceSeries

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 ValueDifferenceSeries

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 ValueDifferenceSeries

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 Serialize for ValueDifferenceSeries

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
