Struct JoinSet

pub struct JoinSet<T> { /* private fields */ }

A wrapper around Tokio’s JoinSet that forwards all API calls while optionally instrumenting spawned tasks and blocking closures with custom tracing behavior. If no tracer is injected via trace_utils::set_tracer, tasks and closures are executed without any instrumentation.
