Network Layers

Where Rama is different from most other typical Tower user cases that we are aware of, is that we wish to use service stacks across layers of the network.

You can read through the 'http service hello' example to see this in effect in a minimal setup. There you can see how there are services on the tcp layer as well as the http layer, and that the Extensions propagates through them all via the input to the service calls.

Abstract Example:

In rama it is truly Services all the way down.

Transport Layer Service Examples

All rama examples can be found in the /examples dir.

Here are some examples that demonstrate working with transport layer services:

• /examples/tcp_listener_layers.rs: an example showing how to create a TCP listener with multiple layers of middleware;
• /examples/tcp_listener_fd_passing.rs: demonstrates real FD passing via SCM_RIGHTS for zero-downtime restarts (Unix-only);
• /examples/tcp_listener_hello.rs: a minimal example demonstrating a TCP listener that responds with a hello message;
• /examples/tcp_nd_json.rs: example demonstrating how to serve a ndjson (Newline Delimited JSON) stream of data over TCP
• /examples/udp_codec.rs: an example showing how to work with UDP using codecs for message framing;
