Constant rama::telemetry::opentelemetry::semantic_conventions::trace::MESSAGING_SYSTEM

pub const MESSAGING_SYSTEM: &'static str;

The messaging system as identified by the client instrumentation.

The actual messaging system may differ from the one known by the client. For example, when using Kafka client libraries to communicate with Azure Event Hubs, the messaging.system is set to kafka based on the instrumentation's best knowledge.
