pub const TE: HeaderName;
Informs the server of transfer encodings willing to be accepted as part of the response.
See also the Transfer-Encoding response header for more details on transfer encodings. Note that chunked is always acceptable for HTTP/1.1 recipients and you that don’t have to specify “chunked” using the TE header. However, it is useful for setting if the client is accepting trailer fields in a chunked transfer coding using the “trailers” value.
