[−][src]Crate greetd_ipc
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.
