Expand description

Extension trait providing additional aggregation methods for iterables with potentially invalid (None) values.

Provided Methods§

Source

fn n_vsum_filter<U, I>(self, mask: I) -> (usize, T::Inner)
where I: IntoIterator<Item = U>, U: IsNone, U::Inner: Cast<bool>, T::Inner: Number,

Computes the sum of valid values filtered by a mask, along with the count of valid elements.

§Arguments
  • mask - An iterable of boolean-like values used to filter the input.
§Returns

A tuple containing the count of valid elements and their sum.

Source

fn n_sum_filter<U, I>(self, mask: I) -> Option<T::Inner>
where I: IntoIterator<Item = U>, U: IsNone, U::Inner: Cast<bool>, T::Inner: Number,

Computes the sum of valid values filtered by a mask.

§Arguments
  • mask - An iterable of boolean-like values used to filter the input.
§Returns

The sum of valid elements, or None if no valid elements are found.

Source

fn vmean_filter<U, I>(self, mask: I, min_periods: usize) -> f64
where I: IntoIterator<Item = U>, U: IsNone, U::Inner: Cast<bool>, T::Inner: Number,

Computes the mean of valid values filtered by a mask.

§Arguments
  • mask - An iterable of boolean-like values used to filter the input.
  • min_periods - The minimum number of valid elements required to compute the mean.
§Returns

The mean of valid elements, or NaN if the number of valid elements is less than min_periods.

Source

fn vkurt(self, min_periods: usize) -> f64
where T::Inner: Number,

Computes the kurtosis of the data.

§Arguments
  • min_periods - The minimum number of valid elements required to compute the kurtosis.
§Returns

The kurtosis of the data, or NaN if the number of valid elements is less than min_periods.

Source

fn vpercentile_of(self, score: T, method: PercentileOfMethod) -> f64
where T::Inner: Number + PartialOrd, T: IsNone,

Computes the percentile rank of a given score relative to a list of scores.

§Arguments
  • score - The score for which the percentile rank is computed.
  • method - The method used for the percentile calculation:
§Returns

The percentile rank of the given score as a f64. Returns NaN if the score is None.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
