Trait polars_core::chunked_array::ops::ChunkShiftFill

pub trait ChunkShiftFill<T, V> {
    fn shift_and_fill(
        &self, 
        periods: i32, 
        fill_value: V
    ) -> Result<ChunkedArray<T>>;
}

Required methods

fn shift_and_fill(&self, periods: i32, fill_value: V) -> Result<ChunkedArray<T>>

Shift the values by a given period and fill the parts that will be empty due to this operation with fill_value.
