Trait for getting and setting the previous time index for various time scales.

This trait extends TimeIndexable and provides a convenient interface for interacting with the “previous” time indices, as opposed to the “current” ones.

Provided Methods

fn get_previous_year_index(&self) -> Option<&usize>

Returns the previous year index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.

fn get_previous_month_index(&self) -> Option<&usize>

Returns the previous month index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.

fn get_previous_week_index(&self) -> Option<&usize>

Returns the previous week index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.

fn get_previous_day_index(&self) -> Option<&usize>

Returns the previous day index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.

fn get_previous_hour_index(&self) -> Option<&usize>

Returns the previous hour index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.

fn get_previous_minute_index(&self) -> Option<&usize>

Returns the previous minute index, if it exists.

Returns

An Option containing a reference to the index, or None if not set.
