Crate ptx_builder

build.rs helper crate for your CUDA experiments.

It helps to automatically build device crate in both single-source and separated-source projects.

Features the crate provide:

• Automatically notify Cargo about device crate sources, so it can reuild on changes,
• Provide output PTX assembly path to Rust via environment variable,
• Rich reporting of device crate errors,
• Hints and troubleshooting for missing tools.

Usage

Simply add the crate as build-dependency:

[build-dependencies]
ptx-builder = "0.5"

And start using it in build.rs script:

use ptx_builder::error::Result;
use ptx_builder::prelude::*;

fn main() -> Result<()> {
    let builder = Builder::new(".")?;
    CargoAdapter::with_env_var("KERNEL_PTX_PATH").build(builder);
}

Now, on the host-side, the PTX assembly can be loaded and used with your favorite CUDA driver crate:

use std::ffi::CString;

let ptx = CString::new(include_str!(env!("KERNEL_PTX_PATH")))?;

// use the assembly contents ...
