Tokio-Trace: Scoped, Structured, Async-Aware Diagnostics - RustConf 2019
Explore a comprehensive conference talk from RustConf 2019 that delves into tokio-trace, a set of Rust libraries providing primitives for recording scoped, structured, and async-aware diagnostics. Learn about the motivation behind tokio-trace, its core concepts, and how it addresses challenges in logging for asynchronous applications. Discover the differences between traditional logging and tokio-trace's structured diagnostics, which model contextual and causal relationships between events. Gain insights into the library's design, its core primitives of spans and events, and how it can be applied in various Rust codebases. Follow along with a live demonstration and understand how tracing actually works, including its compatibility with existing logging systems and its efficient performance with disabled instrumentation. Explore the potential for bootstrapping an ecosystem around tokio-trace and its applications in improving diagnostics for async systems.
