How do I handle memory leaks in async Rust tasks?

The skill covers strategies for breaking Arc reference cycles using Weak pointers and implementing graceful shutdown signals to prevent unbounded task growth.

Can I monitor my Rust async runtime in real-time?

Yes, the skill includes detailed instructions for integrating tokio-console, which allows you to monitor task poll durations, waker operations, and resource utilization live.

What is the best way to profile Tokio performance bottlenecks?

It recommends using structured tracing instrumentation to create spans, which can then be analyzed via flame graphs or tokio-console to find long-running synchronous work blocking the runtime.

How can I test async code that relies on timing?

The skill demonstrates how to use tokio::test with paused time to instantly test timeouts and delayed operations without waiting for real-world intervals.

How do I detect deadlocks in Tokio applications?

This skill provides patterns for implementing consistent lock ordering and utilizing try_lock with timeouts to identify potential deadlocks before they impact production stability.
