Crate sml_rs

Smart Message Language (SML) parser written in Rust.

Modern German power meters periodically send SML-encoded data via an optical interface. The main use-case of this library is to decode that data.

See the transport module for encoding / decoding the SML transport protocol v1 and the parser module for parsing decoded data into SML data structures.

Complete examples of how to use the library can be found on github in the examples folder.

Feature flags

• std (default) — Remove this feature to make the library no_std compatible.
• alloc (default) — Implementations using allocations (alloc::Vec et al.).
• embedded_hal — Allows using pins implementing embedded_hal::serial::Read in SmlReader.
• nb - Enables non-blocking APIs using the nb crate.
