The Tokio project is working on a tracing lib that should be compatible with open tracing

[carllerche]

Tokio is working on Tokio Trace, a scoped, structured logging system:

• Tracking issue.
• Implementation.

The design is decoupled from any specific tracing implementation and enables libraries to instrument themselves. It should enable open trace based subscribers to observe these events and be compatible with the open tracing system.

I thought I would point it out here in case you want to review and provide thoughts.
