Crate dbc_rs 

dbc-rs

A no_std compatible Rust library for parsing and working with DBC (CAN database) files.

Features

• no_std compatible: Works in embedded environments without the standard library
• Minimal dependencies: Only heapless when using heapless feature (zero dependencies with alloc/std)
• Memory efficient: Uses Vec (via alloc) for dynamic collections
• Type-safe: Strong typing for all DBC elements

Usage

use dbc_rs::Dbc;

let dbc_content = r#"VERSION "1.0"

BU_: ECM TCM

BO_ 256 EngineData : 8 ECM
 SG_ RPM : 0|16@0+ (0.25,0) [0|8000] "rpm" TCM
"#;

let dbc = Dbc::parse(dbc_content)?;
