pub fn parse_window_coverage(
value: Option<&Value>,
) -> Result<Vec<WindowCoverage>, String>Expand description
§7.5: parse a coverage array of {base, units} entries. Absent or null is
empty; a non-array, a malformed base, or non-string units are rejected
explicitly instead of silently defaulting. Shared with the Tauri plugin’s
read sidecar.
