Variants

Sum

Sum of the values.

Prod

Product of the values.

Mean

Arithmetic mean.

Min

Smallest value.

Max

Largest value.

Count

Number of non-null values.

Var

Variance with ddof delta degrees of freedom, like numpy.var.

Fields

ddof: usize

Delta degrees of freedom: the divisor is n - ddof.

Std

Standard deviation with ddof delta degrees of freedom, like numpy.std.

Fields

ddof: usize

Delta degrees of freedom: the divisor is n - ddof.

Median

Middle value, with linear interpolation.

Quantile(f64)

Quantile q in [0, 1] with linear interpolation, like numpy.quantile.

Any

true when any value is true or non-zero.

All

true when all values are true or non-zero.

ArgMin

Index of the first minimum along the reduced axis (or the flat index for all axes).

ArgMax

Index of the first maximum along the reduced axis (or the flat index for all axes).

Trait Implementations

impl Copy for Reduction

impl Debug for Reduction

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

Formats the value using the given formatter.

impl PartialEq for Reduction

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
