Struct async_graphql_poem::GraphQLSubscription

pub struct GraphQLSubscription<Query, Mutation, Subscription> { /* fields omitted */ }

A GraphQL subscription endpoint.

Example

use poem::{Route, get};
use async_graphql_poem::GraphQLSubscription;
use async_graphql::{EmptyMutation, Object, Schema, Subscription};
use futures_util::{Stream, stream};

struct Query;

#[Object]
impl Query {
    async fn value(&self) -> i32 {
        100
    }
}

struct Subscription;

#[Subscription]
impl Subscription {
    async fn values(&self) -> impl Stream<Item = i32> {
        stream::iter(vec![1, 2, 3, 4, 5])
    }
}

type MySchema = Schema<Query, EmptyMutation, Subscription>;

let schema = Schema::new(Query, EmptyMutation, Subscription);
let app = Route::new().at("/ws", get(GraphQLSubscription::new(schema)));
