Changelog

Sourced from warp's changelog.

v0.2.1 (January 23, 2020)

• Features:
  • Add close and close_with constructors to warp::ws::Message.
• Fixes:
  • Fix warp::fs filters using a very small read buffer.

v0.2.0 (January 16, 2020)

• Features:
  • Update to std::future, adding async/await support!
  • Add warp::service() to convert a Filter into a tower::Service.
  • Implement Reply for Box<dyn Reply>.
• Changes:
  • Refactored Rejection system (#311).
  • Change path! macro to assume a path::end() by default, with explicit / .. to allow building a prefix (#359).
  • Change warp::path(str) to accept any AsRef<str> argument.
  • Rename "2"-suffixed filters and types (get2 to get, ws2 to ws, etc).
  • Filter::{or, or_else, recover} now require Self::Error=Rejection. This helps catch filters that didn't make sense (like warp::any().or(warp::get())).
  • Change several warp::body filters (#345).
  • Change warp::cors() to return a warp::cors::Builder which still implements Wrap, but can also build a cheaper-to-clone wrapper.
  • Change warp::multipart stream API to allow for errors when streaming.
  • Change warp::sse to no longer return a Filter, adds warp::sse::reply to do what Sse::reply did.
  • Change Server::tls() to return a TLS server builder (#340).
  • Change internal warp::never::Never usage with std::convert::Infallible.
  • Remove warp::ext::set() function (#222).
  • Remove deprecated warp::cookie::optional_value().
