Struct DataPoint 

pub struct DataPoint { /* private fields */ }

One observation of one feature: the instance id, its value and its label.

Implementations

impl DataPoint

pub fn new(tid: usize, value: f64, label: f64) -> Self

An observation of instance tid, not yet indexed.

pub fn tid(&self) -> usize

pub fn value(&self) -> f64

pub fn label(&self) -> f64

pub fn set_unique_value_id(&mut self, value: usize)

Sets the index of the value among the column’s distinct values.

pub fn unique_value_id(&self) -> usize

The index of the value among the column’s distinct values.

Trait Implementations

impl Clone for DataPoint

fn clone(&self) -> DataPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DataPoint

impl Debug for DataPoint

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

Formats the value using the given formatter.

impl Eq for DataPoint

impl Ord for DataPoint

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 DataPoint

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 DataPoint

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.
