| # openprot-mctp-client |
| |
| IPC client for the MCTP server, used by userspace applications under Pigweed (`pw_kernel`). |
| |
| ## Overview |
| |
| This crate provides `IpcMctpClient`, which implements the `MctpClient` trait from `openprot-mctp-api`. It communicates with the MCTP server process over a Pigweed IPC channel using the binary wire protocol defined in `openprot-mctp-api`. |
| |
| Applications (such as the MCTP echo task) use this crate to interact with the MCTP server without needing to know about transport details. |
| |
| ## Key Types |
| |
| - `IpcMctpClient` — implements `MctpClient` via Pigweed IPC; uses `RefCell` for interior mutability so trait methods taking `&self` can mutate internal IPC buffers |
| |
| ## Status |
| |
| The `send_recv` method is currently stubbed, pending Phase 6 integration with `syscall::channel_transact`. |
| |
| ## Dependencies |
| |
| - `openprot-mctp-api` — `MctpClient` trait and wire protocol |
