HTTP frameworks and clients can integrate with TextMapPropagator by providing the object containing the headers, and a getter and setter function for the extraction and injection of values, respectively. Nrcontextgetterr cy)aLCreate a Context from values in the carrier. The extract function should retrieve values from the carrier object using getter, and use values to populate a Context value and return it. Args: getter: a function that can retrieve zero or more values from the carrier. In the case that the value does not exist, return an empty list. carrier: and object which contains values that are used to construct a Context. This object must be paired with an appropriate getter which understands how to extract a value from it. context: an optional Context to use. Defaults to root context if not set. Returns: A Context with configuration found in the carrier. Nr )r rr6r7s r extractzTextMapPropagator.extractrrsettercy)aInject values from a Context into a carrier. inject enables the propagation of values into HTTP clients or other objects which perform an HTTP request. Implementations should use the `Setter` 's set method to set values on the carrier. Args: carrier: An object that a place to define HTTP headers. Should be paired with setter, which should know how to set header values on the carrier. context: an optional Context to use. Defaults to current context if not set. setter: An optional `Setter` object that can set values on the carrier. Nr )r rr6r:s r injectzTextMapPropagator.injectrrcy)a* Gets the fields set in the carrier by the `inject` method. If the carrier is reused, its fields that correspond with the ones present in this attribute should be deleted before calling `inject`. Returns: A set with the fields set in `inject`.
