pub fn parse_query(raw: Option<&str>) -> Result<Vec<(String, String)>, String>Expand description
Parse a raw query string into ordered key/value pairs.
None and the empty string yield no pairs. A non-empty string must be valid
application/x-www-form-urlencoded.
§Errors
Returns an error string when the query cannot be parsed, so the caller can reject the request rather than silently dropping every query-bound field.
