Meterbus Wired Data-Link

Wired M-Bus data-link frames and codecs for Rust.

This crate provides typed, validated frame construction plus exact and streaming decoders for the wired M-Bus link layer defined by EN 13757-2:2018+A1:2023. The default build is no_std and allocation-free. It is designed for masters, meters, bridges, embedded devices, and diagnostic tools.

• Typed ACK, NACK, short, control, and long frames
• no_std, allocation-free codecs with optional alloc
• Exact and incremental stream decoding
• Strict decoding or noise-resynchronizing recovery
• Typed fields and detailed validation errors

Official bindings are available for Node.js, Python, and browser WebAssembly:

Installation

Add the crate without any features for a no_std, allocation-free build:

[dependencies]
meterbus-wired-datalink = "0.0.1"

To use convenience methods that return vectors, enable the optional alloc feature:

[dependencies]
meterbus-wired-datalink = { version = "0.0.1", features = ["alloc"] }

Reference material

Development is guided by the following standards:

The current implementation follows the link-layer frame formats, communication types, addressing rules, and sequencing fields from EN 13757-2:2018+A1:2023. That standard uses the FT1.2 frame format defined by the EN 60870-5 series.
