Implementations

impl FeatureData

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn is_present(&self, ix: usize) -> bool

Get the datum at [row_ix, col_ix] as a Datum

pub fn get(&self, ix: usize) -> Datum

Get the datum at [row_ix, col_ix] as a Datum

pub fn summarize(&self) -> SummaryStatistics

Get the summary statistic for a column

Trait Implementations

impl Clone for FeatureData

fn clone(&self) -> FeatureData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FeatureData

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FeatureData

fn eq(&self, other: &FeatureData) -> 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 Serialize for FeatureData

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for FeatureData
