+/// `TE` header, defined in
+/// [RFC7230](http://tools.ietf.org/html/rfc7230#section-4.3)
+///
+/// As RFC7230 states, "The "TE" header field in a request indicates what transfer codings,
+/// besides chunked, the client is willing to accept in response, and
+/// whether or not the client is willing to accept trailer fields in a
+/// chunked transfer coding."
+///
+/// For HTTP/1.1 compliant clients `chunked` transfer codings are assumed to be acceptable and
+/// so should never appear in this header.
+///
+/// # ABNF
+///
+/// ```text
+/// TE        = "TE" ":" #( t-codings )
+/// t-codings = "trailers" | ( transfer-extension [ accept-params ] )
+/// ```
+///
+/// # Example values
+/// * `trailers`
+/// * `trailers, deflate;q=0.5`
+/// * ``

+/// # Examples
