lin-ldf 0.0.23

Parser for LDF files that describe automotive LIN bus networks.
Documentation
# lin-ldf

LIN Description File (.ldf) parser using Rust's `nom` parser combinator library. LIN is an automotive network protocol used for communication between ECUs in a vehicle. The LDF file is used to describe the network configuration, including the different nodes and signals sent between them.
