pub trait ChunkShiftFill<T: PolarsDataType, V> {
// Required method
fn shift_and_fill(&self, periods: i64, fill_value: V) -> ChunkedArray<T>;
}
Expand description
Shift the values of a ChunkedArray
by a number of periods.
Required Methods§
Sourcefn shift_and_fill(&self, periods: i64, fill_value: V) -> ChunkedArray<T>
fn shift_and_fill(&self, periods: i64, fill_value: V) -> ChunkedArray<T>
