In this stream, we peel back the crust on the tracing crate —
[ Ссылка ] — and explore its interface,
structure, and mechanisms. We talk about spans, events, their attributes
and fields, and how to think about them in async code. We also dig into
into what subscribers are, how they pick up events, and how you can
construct your own subscribers through the layer abstraction.
For more details about tracing, see [ Ссылка ].
