This is only used when injecting a trace context as internally implemented by RpcClientHandler. Calls during sampling or parsing are invalid and may be ignored by instrumentation.

Header based requests will use headers, but this could set RPC envelopes or even binary data.

Parameters:

value - value used for Propagation.Setter.put(R, K, java.lang.String)
