Core primitives for application-level tracing.
tracing is a framework for instrumenting Rust programs to collect
structured, event-based diagnostic information. This crate defines the core
The crate provides:
Spanidentifies a span within the execution of a program.
Eventrepresents a single event within a trace.
Subscriber, the trait implemented to collect trace data.
Dispatchallows span events to be dispatched to
In addition, it defines the global callsite registry and per-thread current dispatcher which other components of the tracing system rely on.
Application authors will typically not use this crate directly. Instead, they
will use the
tracing crate, which provides a much more fully-featured
API. However, this crate's API will change very infrequently, so it may be used
when dependencies must be very stable.
