• Add Conditional and Range request support for warp::fs filters.
• Relaxed bounds on Rejection::with to no longer need to be Sized.
• Add warp::path::peek() which gets the unmatched tail without adjusting the currently matched path.

Features:

• Serve index.html automatically with warp::fs::dir filter.
• Include last-modified header with warp::fs filters.
• Add warp::redirect to easily reply with redirections.
• Add warp::reply::{with_status, with_header} to wrap impl Replys directly with a new status code or header.
• Add support for running a warp Server with a custom source of incoming connections.
  • Server::run_incoming to have the runtime started automatically.
  • Server::serve_incoming to get a future to run on existing runtime.
  • These can be used to support Unix Domain Sockets, TLS, and other transports.
• Add Rejection::into_cause() to retrieve the original error of a rejection back.
• Add Rejection::json() to convert a rejection into a JSON response.

Fixes

• Internal errors in warp that result in rendering a 500 Internal Server Error are now also logged at the error level.

• Add warp::reply::with::headers(HeaderMap) filter wrapper.
• Add warp::cookie::optional() to get an optional cookie value.
• Add warp::path::full() to be able to extract the full request path without affecting route matching.
• Add graceful shutdown support to the Server.
• Allow empty query strings to be treated as for warp::query().

• Add warp::reject::forbidden() to represent 403 Forbidden responses.
• Add Rejection::with(cause) to customize rejection messages.

• Fix warp::body::form to allow charsets in the content-type header.

• Implemented Reply for Response<impl Into<hyper::Body>, allowing streaming response bodies.
• Add warp::body::stream() filter to access the request body as an impl Stream.
• Add warp::ws2() as a more flexible websocket filter.
  • This allows passing other extracted values to the upgrade callback, such as a value from a header or path.
  • Deprecates warp::ws(), and ws2() will become ws() in 0.2.
• Add warp::get2(), warp::post2(), warp::put2(), and warp::delete2() as more standard method filters that are used via chaining instead of nesting.
  • get(), post(), put(), and delete() are deprecated, and the new versions will become them in 0.2.
• Add Filter::unify() for when a filter returns Either<T, T>, converting the Either into the inner T, regardless of which variant it was.

  • This requires that both sides of the Either be the same type.

  • This can be useful when extracting a value that might be present in different places of the request.

    // Allow `MyId` to be a path parameter or a header...
    let id = warp::path::param::<MyId>()
        .or(warp::header::<MyId>())
        .unify();
    
    // A way of providing default values...
    let dnt = warp::header::<bool>("dnt")
        .or(warp::any().map(|| true))
        .unify();

• Add content-type header automatically to replies from file and dir filters based on file extension.
• Add warp::head(), warp::options(), and warp::patch() as new Method filters.
• Try to use OS blocksize in warp::fs filters.

• Chaining filters that try to consume the request body will log that the body is already consumed, and return a 500 Internal Server Error rejection.

• add warp::query::raw() filter to get query as a String.
• add Filter::recover() to ease customizing of rejected responses.
• add warp::header::headers_clone() filter to get a clone of request's HeaderMap.
• add warp::path::tail() filter to get remaining "tail" of the request path.

• URL decode path segments in warp::fs filters.
