| //! # MCTP Loopback Transport Binding |
| //! |
| //! This crate provides a loopback transport binding for the MCTP server, |
| //! enabling direct server-to-server communication without physical transport. |
| //! |
| //! It implements [`mctp_lib::Sender`] for outbound MCTP packets and provides |
| //! a shared buffer mechanism for bidirectional packet exchange between two |
| //! MCTP endpoints. |
| //! |
| //! ## Design |
| //! |
| //! Unlike I2C transport which requires encoding/decoding with transport headers |
| //! and PEC, the loopback transport works with raw MCTP packets. This makes it |
| //! simpler and more efficient for in-memory communication. |
| //! |
| //! The [`LoopbackPair`] manages two unidirectional packet queues (A→B and B→A). |
| //! Each endpoint gets a [`LoopbackSender`] that writes to the appropriate queue. |
| //! The application polls the pair to transfer packets to the receiving server. |
