v0.1.8

• Features:

  • Improved flexibility of Rejection system.

    The Rejection type can now nest and combine arbitrary rejections,
    so it is no longer bound to a small set of meanings. The ranking of
    status codes is still used to determine which rejection gets priority.

    A different priority can be implemented by handling rejections with
    a Filter::recover, and searching for causes in order via
    Rejection::find_cause.

    • Adds warp::reject::custom() to create a Rejection with
      any Into<Box<std::error::Error>>. These rejections should be
      handled with an eventual Filter::recover. Any unhandled
      custom rejections are considered a server error.
    • Deprecates Rejection::with. Use custom rejections instead.
    • Deprecates Rejection::into_cause, as it can no longer work. Always
      returns Err(Rejection).
    • Deprecates Rejection::json, since the format needed is too generic.
      The errors.rs example shows how to send custom JSON when recovering
      from rejections.
    • Deprecates warp::reject(), since it current signals a 400 Bad Request, but in newer versions, it will signal 404 Not Found.
      It's deprecated simply to warn that the semantics are changing,
      but the function won't actually go away.
    • Deprecates reject::bad_request(), reject::forbidden(), and
      reject::server_error(). Uses custom rejections instead.

  • Renamed warp::path::index to warp::path::end.
