pub fn select(
range: Option<&str>,
if_range: Option<&str>,
etag: &str,
len: u64,
) -> SelectionExpand description
Select the bytes for Range and If-Range against a representation of
len bytes whose strong validator is etag. An invalid Range is
ignored (never a 400), a multi-range request is a strict 200, and only a
matching strong If-Range ETag enables slicing.
