Extracts the trace ID and trace state from an incoming request represented by the carrier. For example, from the headers of an HTTP request.

public:
 abstract void ExtractTraceIdAndState(System::Object ^ carrier, System::Diagnostics::DistributedContextPropagator::PropagatorGetterCallback ^ getter, [Runtime::InteropServices::Out] System::String ^ % traceId, [Runtime::InteropServices::Out] System::String ^ % traceState);
public abstract void ExtractTraceIdAndState (object? carrier, System.Diagnostics.DistributedContextPropagator.PropagatorGetterCallback? getter, out string? traceId, out string? traceState);
abstract member ExtractTraceIdAndState : obj * System.Diagnostics.DistributedContextPropagator.PropagatorGetterCallback * string * string -> unit
Public MustOverride Sub ExtractTraceIdAndState (carrier As Object, getter As DistributedContextPropagator.PropagatorGetterCallback, ByRef traceId As String, ByRef traceState As String)
