`Async-graphql-actix-web` provides an implementation of `actix_web::FromRequest` for `GQLRequest`. This is actually an abstraction around `QueryBuilder` and you can call `GQLRequest::into_inner` to convert it into a `QueryBuilder`。
`WSSubscription` is an Actor that supports WebSocket subscriptions。
## Request example
When you define your `actix_web::App` you need to pass in the Schema as data.
