Struct async_graphql::extensions::ApolloTracing

pub struct ApolloTracing { /* fields omitted */ }

This is supported on crate feature apollo_tracing only.

Apollo tracing extension for performance tracing

Apollo Tracing works by including data in the extensions field of the GraphQL response, which is reserved by the GraphQL spec for extra information that a server wants to return. That way, you have access to performance traces alongside the data returned by your query. It's already supported by Apollo Engine, and we're excited to see what other kinds of integrations people can build on top of this format.
