Enum Scalar 

pub enum Scalar {
    F64(f64),
    F32(f32),
    I64(i64),
    I32(i32),
    Bool(bool),
}

The result of a dtype-preserving scalar reduction (Column::sum etc.), carrying the value in its pandas result dtype so the binding can box it as the matching numpy scalar (np.int64 / np.float64 / np.bool_).

Variants

F64(f64)

A float64 result (mean, an f64 column’s sum/min/max, …).

F32(f32)

A float32 result (an f32 column’s sum/min/max).

I64(i64)

An int64 result (an i64/bool column’s sum/prod, an i64 min/max).

I32(i32)

An int32 result (an i32 column’s sum/prod/min/max).

Bool(bool)

A boolean result (a bool column’s min/max).

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Scalar

impl Debug for Scalar

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

Formats the value using the given formatter.

impl PartialEq for Scalar

fn eq(&self, other: &Scalar) -> 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.
