ContextPropagators.type
A TextMapPropagator that extracts a specified collection of fields and stores them in a context, and extracts them from a context later for injection.
A TextMapPropagator that extracts a specified collection of fields and stores them in a context, and extracts them from a context later for injection. It does not interact with telemetry.

Offers a way to get a string value associated with a given key.
Offers a way to get a string value associated with a given key.
A type class can be implemented for any data structure that stores key-value pairs.
Implicit instances of TextMapGetter are provided for scala.collection.Map and scala.collection.Seq types. The behavior of TextMapGetter[Seq[(String, String)]] when duplicate keys are present is unspecified, and may change at any time. In particular, if the behavior of Seq types with duplicate keys is ever specified by open telemetry, the behavior of such implicit instances will be made to match the specification.

TextMapGetter.type
The process of propagating data across process boundaries involves injecting and extracting values in the form of text into carriers that travel in-band.
The process of propagating data across process boundaries involves injecting and extracting values in the form of text into carriers that travel in-band.
The encoding used for this process is expected to conform to HTTP Header Field semantics, and values are commonly encoded as request headers for RPC/HTTP requests.
The carriers used for propagating the data are typically HTTP requests, and the process is often implemented using library-specific request interceptors. On the client side, values are injected into the carriers, while on the server side, values are extracted from them.
