pub fn route(req: &Request) -> Route<'_>Expand description
Classifies a request by method and :protocol.
The pseudo-header is read straight off the Request, as the tunnels read
every other field of one (D78). It used to arrive through a classifier in
crate::h3api, but that enum was this one’s three variants under other
names and existed only to be translated into them on the next line.
