Apollo Tracing

Apollo Tracing provides performance analysis results for each step of query. This is an extension to Schema, and the performance analysis results are stored in QueryResponse.

To enable the Apollo Tracing extension, add the extension when the Schema is created.

use async_graphql::*;
use async_graphql::extensions::ApolloTracing;

let schema = Schema::build(Query, EmptyMutation, EmptySubscription)
    .extension(ApolloTracing::default) // Enable ApolloTracing extension
    .finish();
