pub fn content_range_header_value(
status_code: i16,
content_range: &ContentRange,
) -> Option<String>Expand description
The Content-Range value for a single-part body, or None when the
response shouldn’t carry one. RFC 9110 §14.4 gives Content-Range meaning
only on 206 Partial Content (and 416, which rws answers with a plain
error body), so full 200 responses get no such header. range.end is
inclusive.
