greetd IPC protocol library

This library implements the greetd IPC protocol.

The library exposes a Request and a Response enum, representing the valid protocol messages. Furthermore, codec implementations are available to serialize these to/from both sync and async readers/writers. The availability of these are controlled by feature flags.

Additional types are part of the different request and response values.

See agreety for a simple example use of this library.

Format

The message format is as follows:

+----------+-------------------+
| len: u32 | JSON payload: str |
+----------+-------------------+

Length is in native byte-order. The JSON payload is a variant of the Request or Response enums.

Request and response types

See Request and Response for information about the request and response types, as well as their serialization.
