Execution-Time Benchmarks Report ⏱️Execution-time results for samples comparing the following branches/commits: Execution-time benchmarks measure the whole time it takes to execute a program. And are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are shown in red. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard. Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph). gantt

Summary of changes
Add a public API that allows users to access and modify baggage.
Reason for change
Adding support for OpenTelemetry baggage.
Implementation details
Add a static
Baggageclass toDatadog.Trace.Manualwith a singleCurrentstatic property:The internal
BaggageimplementsIDictionary<string, string>, so no duck-typing is required.With IL-rewriting, this property is modified at run time:
Baggage.CurrentBaggageobject with the given key/value pairs and sets the internalBaggage.CurrentWhen IL-rewriting is not enabled, this property returns a standard
Dictionary<string, string>. This will behave the same as the internalBaggage, but no propagation will occur.Test coverage
Added tests in
Samples.ManualInstrumentation.
