Struct finql::time_period::TimePeriod

pub struct TimePeriod { /* fields omitted */ }

Methods

impl TimePeriod

Transform a string into a TimePeriod

pub fn add_to(&self, date: NaiveDate, cal: Option<&Calendar>) -> NaiveDate

Add time period to a given date. The function call will panic is the resulting year is out of the valid range or if not calendar is provided in case of BusinessDaily time periods

pub fn sub_from(&self, date: NaiveDate, cal: Option<&Calendar>) -> NaiveDate

Substract time period from a given date.

pub fn inverse(&self) -> TimePeriod

Substract time period from a given date.

pub fn frequency(&self) -> Result<u16, TimePeriodError>

Returns the frequency per year, if this is possible, otherwise return error
