var MessagingDestinationTopicKind = semconv.MessagingDestinationKindTopic.Value.AsString()

MessagingDestinationTopicKind is effectively const, but isn't a const from upstream.

Types

type GrpcAppendSpanAttributesFn

type GrpcAppendSpanAttributesFn interface {
	// AppendSpanAttributes appends attributes to the map used for the span in tracing for the gRPC method.
	AppendSpanAttributes(rpcMethod string, m map[string]string)
}

GrpcAppendSpanAttributesFn is the interface that applies to gRPC requests that add span attributes.
