MSRT

MSRT means MSRT.

MSRT is a common serial realtime transport protocol for MCU, robot, drone, and host-side systems. It is message-driven, channel-based, engine-friendly, and designed for realtime links with partial reliability.

This repository is currently in the protocol-standard stage. The msrt crate defines the shared protocol boundary only. MCU ports and host-side operating-system integrations are intentionally outside this repository for now.

The same standard protocol should be usable from two future implementation environments:

• MCU environments, typically no_std and often allocation-constrained.
• Host environments, using normal Rust with an operating system.

Those environments must adapt to the protocol. The protocol must not depend on those environments.

See SPEC.md for the current standard boundary. See ROADMAP.md for the current scaffold scope and next phases.

Crate

msrt is a single portable crate for the protocol standard. It enables std by default for host ergonomics, but the protocol core remains usable without std:

# Host/default.
msrt = "0.1"

# MCU/no_std.
msrt = { version = "0.1", default-features = false }

Internal protocol boundaries live as modules:

• core: core protocol primitives.
• error: shared protocol error types.
• reliability: reliability traits and modules.
• engine: protocol engine boundary for send, receive, response, and progress.
• wire: wire envelope boundaries for byte stream transport.

No MCU HAL, async executor, serial driver, operating-system adapter, simulator, CLI implementation, or separate channel/frame crate is included at this stage.
