Function polars::prelude::group_by_windows

pub fn group_by_windows(
    window: Window,
    time: &[i64],
    closed_window: ClosedWindow,
    tu: TimeUnit,
    tz: &Option<String>,
    include_lower_bound: bool,
    include_upper_bound: bool,

) -> (Vec<[u32; 2]>, Vec<i64>, Vec<i64>)

Available on crate feature temporal only.

Window boundaries are created based on the given Window, which is defined by:

• every
• period
• offset

And every window boundary we search for the values that fit that window by the given ClosedWindow. The groups are return as GroupTuples together with the lower bound and upper bound timestamps. These timestamps indicate the start (lower) and end (upper) of the window of that group.

If include_boundaries is false those lower and upper vectors will be empty.
