strSlice
The code-point slice [start, end) of each string (ADR-2026-10-23-12): negative indices count from the end (Python/Polars semantics); out-of-range clamps; nulls propagate. A slice clamps where take throws - the documented distinction (a slice is not an index).
Parameters
s | the STRING Series |
start | the first code point (negative: from the end) |
end | the exclusive end (negative: from the end) |
Returns
the sliced STRING Series.
