Module trace_utils 

Structs

NoopTracer 🔒

A no-op tracer that does not modify or instrument any futures or closures. This is used as a fallback if no custom tracer is set.

Enums

JoinSetTracerError

A custom error type for tracer injection failures.

Statics

GLOBAL_TRACER 🔒

Global storage for an injected tracer. If no tracer is injected, a no-op tracer is used instead. This ensures that calls to trace_future or trace_block never panic due to missing instrumentation.

NOOP_TRACER 🔒

A no-op tracer singleton that is returned by get_tracer if no custom tracer has been registered.

Traits

JoinSetTracer

A trait for injecting instrumentation into either asynchronous futures or blocking closures at runtime.

Functions

get_tracer 🔒

Return the currently registered tracer, or the no-op tracer if none was registered.

set_join_set_tracer

Set the custom tracer for both futures and blocking closures.

trace_block

Optionally instruments a blocking closure with custom tracing.

trace_future

Optionally instruments a future with custom tracing.
