Safe Rust wrappers for the CUDA Driver API.

This crate takes the raw FFI in [baracuda_cuda_sys] and dresses it up with RAII handles, typed memory, lifetime-checked slices, and a kernel launch builder. It deliberately does not hide the Driver-API model: contexts are explicit, modules are explicit, streams are explicit.

Quickstart

use baracuda_driver::{Context, Device, DeviceBuffer, Module, Stream};

# fn demo() -> baracuda_driver::Result<()> {
let device = Device::get(0)?;
let ctx = Context::new(&device)?;
let stream = Stream::new(&ctx)?;
let host_data: Vec<f32> = (0..1024).map(|i| i as f32).collect();
let device_data = DeviceBuffer::from_slice(&ctx, &host_data)?;
let mut back = vec![0.0f32; host_data.len()];
device_data.copy_to_host(&mut back)?;
stream.synchronize()?;
assert_eq!(host_data, back);
# Ok(())
# }

Modules

• [device] — [Device] enumeration and attributes.
• [context] — [Context] (explicit CUDA contexts + primary-context reuse).
• [stream] — [Stream], ordered async work queues.
• [event] — [Event], synchronization and timing.
• [memory] — [DeviceBuffer<T>], [DeviceSlice<'_, T>], [DeviceSliceMut<'_, T>].
• [module] — [Module], [Function] (PTX/CUBIN loading).
• [launch] — [launch::LaunchBuilder] for cuLaunchKernel.
• [init()] — init() helper and driver version queries.
