pub fn compute_content_hash(
src_dir: &Path,
i18n_toml_path: Option<&Path>,
) -> StringExpand description
Compute blake3 hash of all .rs files in a source directory, plus the i18n.toml file.
Used for staleness detection - saving a file without modifications won’t change the hash, avoiding unnecessary rebuilds.
The i18n_toml_path parameter includes the i18n.toml configuration file
in the hash, so changes to settings like fluent_feature trigger rebuilds.
