Expand description
§TextMapPropagator
TextMapPropagator
performs the injection and extraction of a cross-cutting concern value as
string key/values pairs into carriers that travel in-band across process boundaries.
The carrier of propagated data on both the client (injector) and server (extractor) side is usually an HTTP request.
In order to increase compatibility, the key/value pairs MUST only consist of US-ASCII characters that make up valid HTTP header fields as per RFC 7230.
