Struct Frequency 

pub struct Frequency { /* private fields */ }

A regular time step: step times a calendar period, for example 6 hours.

Implementations

impl Frequency

pub fn new(step: u32, period: TimePeriod) -> Result<Self>

A frequency of step periods. step must be at least 1.

pub fn parse(text: &str) -> Result<Self>

Parse a pandas frequency string, for example "6h", "1D" or "3MS".

The aliases are YS, MS, D, h, min and s, with an optional step in front. End-anchored aliases such as M and Y are not supported.

pub fn step(&self) -> u32

The number of periods per bin.

pub fn period(&self) -> TimePeriod

The calendar period.
