- consider `juniper_graphql_transport_ws` crate on CI
- implement auto-selection of protocol in `juniper_warp` crate
- support `graphql-transport-ws` protocol in `juniper_actix` crate
- implement auto-selection of protocol in `juniper_actix` crate
Additionally:
- move `examples/warp_subscriptions` into `juniper_warp/examples/subscription.rs`
- move `examples/actix_subscriptions` into `juniper_actix/examples/subscription.rs`
- move `examples/basic_subscriptions` into `juniper_subscriptions/examples/basic.rs`
- bump up MSRV of `juniper_actix` crate to 1.68
- set 1.62 Rust as MSRV
- use new fmt syntax where possible
- refactor `.to_owned()`, `.to_string()` and `.into()` usage
- rename `IntoResolvable::into()` as `IntoResolvable::into_resolvable()` to disambiguate with `Into::into()`
- use `#[derive(Default)]` for enums where possible
- use `bool::then_some()` where possible
- preserve and reuse defined impl blocks in #[graphql_object] and #[graphql_subscription] macros expansion
- allow renaming `ScalarValue` type parameter in expanded code via `scalar = S: ScalarValue` syntax
Additionally:
- rename `rename` attribute's argument to `rename_all`
- support `rename_all` in #[graphql_interface] macro
