+   TCP is a stream based protocol, so the framework provides building blocks to parse telemetry
+   from an arbitrary bytestream. Two concrete implementations are provided:
+    - [TCP spacepackets server](https://docs.rs/satrs-core/0.1.0-alpha.1/satrs_core/hal/std/tcp_server/struct.TcpSpacepacketsServer.html)
+      to parse tightly packed CCSDS Spacepackets.
