openprot-mctp-api

Platform-independent MCTP types and traits crate.

Overview

This crate defines the core API contract between MCTP clients and the MCTP server. It provides traits for client operations, listener management, and request/response channels, as well as the binary IPC wire protocol used for inter-process communication.

Key Types

• Handle — opaque handle for listeners, requests, or response channels
• RecvMetadata — metadata from a successful receive (msg_type, tag, remote_eid, payload_size, etc.)
• MctpError / ResponseCode — error types (Success, InternalError, NoSpace, AddrInUse, TimedOut, BadArgument, ServerRestarted)

Traits

• MctpClient — main client interface (req, listener, get/set EID, recv, send, drop_handle)
• MctpListener — receiving incoming MCTP messages of a specific type
• MctpReqChannel — request/response channels
• MctpRespChannel — response channels

Wire Protocol

The wire module implements binary request/response encoding for IPC communication between userspace processes and the MCTP server.

Dependencies

• zerocopy — zero-copy serialization
• heapless — no_std collections

This crate is no_std compatible.
