Warp
Async-graphql-warp提供了两个Filter，graphql和graphql_subscription。
graphql用于执行Query和Mutation请求，它提取GraphQL请求，然后输出一个包含async_graphql::Schema和async_graphql::Request元组，你可以在之后组合其它Filter，或者直接调用Schema::execute执行查询。
graphql_subscription用于实现基于Web Socket的订阅，它输出warp::Reply。
请求例子
# extern crate async_graphql_warp;
# extern crate async_graphql;
# extern crate warp;
# use async_graphql::*;
# use std::convert::Infallible;
# use warp::Filter;
# struct QueryRoot;
# #[Object]
# impl QueryRoot { async fn version(&self) -> &str { "1.0" } }
# async fn other() {
type MySchema = Schema<QueryRoot, EmptyMutation, EmptySubscription>;
let schema = Schema::new(QueryRoot, EmptyMutation, EmptySubscription);
let filter = async_graphql_warp::graphql(schema).and_then(|(schema, request): (MySchema, async_graphql::Request)| async move {
// 执行查询
let resp = schema.execute(request).await;
// 返回结果
Ok::<_, Infallible>(async_graphql_warp::GraphQLResponse::from(resp))
});
warp::serve(filter).run(([0, 0, 0, 0], 8000)).await;
