Debug routes about warp

[seanmonstar]

If you enable logging (not even using the warp::log filter, just setting up a logger like pretty_env_logger and setting RUST_LOG=warp), you can see trace logs of filters trying to apply themselves.

I do think it'd be quite useful to be able to implement fmt::Debug for the filters, so you can print out a tree of what exists...

I wasn't aware that warp uses log underneath, i found out when checking the source of warp::log. The output is really useful!

If something like a cookbook is planned, a section about debugging paths etc. would be really helpful :)

I might want to take a shot at the debug view: A list of possible paths with {:?} and a tree with the pretty printed debug view {:#?}

Have you looked at the log filter? It does partially what you need:

warp/examples/todos.rs

Line 98 in 25e6c4e

let routes = api.with(warp::log("todos"));

Haven't seen that one, thanks
