rust-lcm-codegen
Generates Rust de/serialization code from LCM type specification files.
Overview
This is a sub-project of rust-lcm-codec which specifically handles the
code generation which provides the Rust API to LCM encoded data. It is intended to be
usable from a Cargo build.rs
script.
Getting Started
This library requires a Rust toolchain. The recommended toolchain management system in Rust is rustup.
Once rustup is installed, you can build for your local device with:
cargo build
Usage
Add the following dependencies to your Rust project's Cargo.toml
:
[build-dependencies]
rust-lcm-codegen = "0.1.0"
Import rust-lcm-codegen:generate
in your Rust project's build.rs
file,
and point the generate
function at your .lcm
schemas and desired
output location for the generated code:
use rust_lcm_codegen::generate;
use std::env;
use std::fs::File;
use std::io::Read;
use std::path::Path;
fn main() {
println!("cargo:rerun-if-changed=../schemas");
println!("cargo:rerun-if-changed=../../src");
println!("cargo:rerun-if-changed=../../../rust-lcm-codegen");
let schema_files = vec![
"./schemas/example_schema_a.lcm",
"path/to/schemas/example_schema_b.lcm",
];
let out_dir = env::var("OUT_DIR").expect("OUT_DIR");
let out_path = Path::join(Path::new(&out_dir), "generated_lcm.rs");
generate(schema_files, &out_path);
}
Tests
To run the tests for this project make sure you're in /rust-lcm-codec/rust-lcm-codegen
and then run:
