Module rama::telemetry::opentelemetry::baggage

Primitives for sending name/value data across system boundaries.

Baggage is used to annotate telemetry, adding context and information to metrics, traces, and logs. It is a set of name/value pairs describing user-defined properties. Each name in Baggage is associated with exactly one value.

Main types in this module are:
