CAN DBC code generator for Rust

Generates Rust messages from a dbc file.

⚠️ This is experimental - use with caution. Breaking changes will happen when you least expect it. ⚠️

Installation

With cargo:

bash cargo install dbc-codegen-cli --git https://github.com/technocreatives/dbc-codegen --branch main

Usage

Generate messages.rs from example.dbc:

bash dbc-codegen testing/dbc-examples/example.dbc dir/where/messages_rs/file/is/written

Field/variant rename rules

If some field name starts with a non-alphabetic character or is a Rust keyword then it is prefixed with x.

For example:

VAL_ 512 Five 0 "0Off" 1 "1On" 2 "2Oner" 3 "3Onest";

…is generated as:

rust pub enum BarFive { X0off, X1on, X2oner, X3onest, Other(bool), }

Type here:

SG_ Type : 30|1@0+ (1,0) [0|1] "boolean" Dolor

…conflicts with the Rust keyword type. Therefore we prefix it with x:

rust pub fn xtype(&self) -> BarType { match self.xtype_raw() { false => BarType::X0off, true => BarType::X1on, x => BarType::Other(x), } }
