# NOTE: `data` feature (polars) is excluded because polars-ops 0.46–0.53 has a build.rs that
# unconditionally enables `feature="nightly"` on nightly compilers, then uses
# `core::unicode::{Case_Ignorable, Cased}` which was removed in Rust nightly 1.97+.
# Upstream fix: https://github.com/pola-rs/polars/commit/67422be6 (not yet published to crates.io).
# Re-enable `data` once polars releases a version containing this fix.
