Struct Float64Column 

pub struct Float64Column { /* private fields */ }

A column of f64 values where any non-finite value (NaN, ±inf) is a gap. Reading a gap gives None.

Implementations

impl Float64Column

pub fn from_values(values: Vec<f64>) -> Self

Build from raw values; non-finite values become gaps.

pub fn from_options(values: impl IntoIterator<Item = Option<f64>>) -> Self

Build from optional values; None is a gap.

pub fn len(&self) -> usize

Number of values.

pub fn is_empty(&self) -> bool

true when there are no values.

pub fn get(&self, i: usize) -> Option<f64>

The value at i, or None for a gap. Panics if i is out of range.

pub fn values(&self) -> &[f64]

The raw buffer: gaps are non-finite values.

pub fn all_finite(&self) -> bool

True when the column has no gaps.

pub fn missing_count(&self) -> usize

Number of gaps.

pub fn iter(&self) -> impl Iterator<Item = Option<f64>> + '_

Iterate as Option<f64>.

Trait Implementations

impl Clone for Float64Column

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Float64Column

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

Formats the value using the given formatter.

impl From<Float64Column> for ColumnData

fn from(c: Float64Column) -> Self

Converts to this type from the input type.

impl PartialEq for Float64Column

Two number columns are equal when they hold the same values, bit for bit (so -0.0 and 0.0 differ), and gaps in the same rows, however each gap is stored (NaN or an infinity).

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

Equality operator ==.

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

Inequality operator !=.
