Walkthrough

Added documentation and examples for option_string. The documentation states that deserialized null becomes None, whitespace-only strings become Some(""), and missing fields require #[serde(default)] to deserialize as None. The implementation is unchanged.

Full details: Title check

Explanation

The title "docs: explain optional string trimming behavior" names the documentation change. The raw summary says the PR documents how option_string handles null and whitespace-only values, and that a missing field needs #[serde(default)]. The title mentions trimming, but the PR does not change trimming. It documents that whitespace-only strings become Some(""), so the title partly misdescribes the change. It still refers to a real aspect of the change, so the check passes.

Full details: Description check

Explanation

The description states that it explains how option_string handles null and whitespace-only values and that #[serde(default)] is needed for a missing field. It also lists doc test and rustdoc build results. This matches the changeset, which adds documentation and examples to crates/detrim/src/string.rs.
