Implementations

impl Window

pub fn new(every: Duration, period: Duration, offset: Duration) -> Window

pub fn truncate( &self, tu: TimeUnit, t: i64, tz: Option<&Tz>, ) -> Result<i64, PolarsError>

Truncate the given timestamp in tu by the window boundary.

pub fn round( &self, tu: TimeUnit, t: i64, tz: Option<&Tz>, ) -> Result<i64, PolarsError>

Round the given timestamp in tu by the window boundary.

pub fn get_earliest_bounds( &self, tu: TimeUnit, t: i64, closed_window: ClosedWindow, tz: Option<&Tz>, ) -> Result<Bounds, PolarsError>

returns the bounds for the earliest window bounds that contains the given time t. For underlapping windows that do not contain time t, the window directly after time t will be returned.

pub fn get_overlapping_bounds_iter<'a>( &'a self, boundary: Bounds, closed_window: ClosedWindow, tu: TimeUnit, tz: Option<&'a Tz>, start_by: StartBy, origin: Option<i64>, ) -> Result<BoundsIter<'a>, PolarsError>

pub fn first_window_start( &self, t0: i64, closed_window: ClosedWindow, tu: TimeUnit, tz: Option<&Tz>, start_by: StartBy, ) -> Result<i64, PolarsError>

The start of the first window for data whose first value is t0, as placed by start_by, every and offset.
