Code

public abstract ISet<string> Fields { get; }

Gets the list of headers used by propagator. The use cases of this are: * allow pre-allocation of fields, especially in systems like gRPC Metadata * allow a single-pass over an iterator (ex OpenTracing has no getter in TextMap).

protected TextMapPropagator()

public abstract PropagationContext Extract<T>(PropagationContext context, T carrier, Func<T, string, IEnumerable<string>> getter)

Extracts the context from a carrier.

public abstract void Inject<T>(PropagationContext context, T carrier, Action<T, string, string> setter)

Injects the context into a carrier.
