Enum Labels 

pub enum Labels {
    Number(Vec<f64>),
    String(StringColumn),
}

Interval labels: numbers or text, one kind for the whole key, as in pond-ts. Every row has a label (no gaps). Build them with .into() from Vec<f64>, Vec<i64>, Vec<&str> or Vec<String>.

Variants

Number(Vec<f64>)

Number labels. aggregate labels each bucket with its start, in epoch milliseconds. Must be finite.

String(StringColumn)

Text labels.

Implementations

impl Labels

pub fn len(&self) -> usize

Number of values.

pub fn is_empty(&self) -> bool

true when there are no rows.

pub fn numbers(&self) -> Option<&[f64]>

Number labels, or None for text labels.

pub fn strings(&self) -> Option<&StringColumn>

Text labels, or None for number labels.

Trait Implementations

impl Clone for Labels

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 Labels

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

Formats the value using the given formatter.

impl From<StringColumn> for Labels

fn from(c: StringColumn) -> Self

Converts to this type from the input type.

impl From<Vec<&str>> for Labels

fn from(v: Vec<&str>) -> Self

Converts to this type from the input type.

impl From<Vec<String>> for Labels

fn from(v: Vec<String>) -> Self

Converts to this type from the input type.

impl From<Vec<f64>> for Labels

fn from(v: Vec<f64>) -> Self
