OBRAH

OBRAH (OpenCL But Rusty And High-level) is a Rust crate built on top of OBWIO(crates.io: OBWIO), providing a high-level, ergonomic interface for OpenCL. It abstracts low-level C bindings, letting you perform GPU computations with minimal boilerplate.

Overview

OBRAH provides an easy-to-use API for:

• Creating OpenCL contexts and command queues
• Loading kernels from .cl files
• Allocating and managing GPU buffers
• Running kernels and retrieving results

It is ideal for Rust developers who want GPU acceleration without dealing with raw OpenCL FFI.

Features

• High-level Rust interface for OpenCL
• Built on OBWIO for cross-platform GPU support
• Simple buffer management (buffer\_write, to\_gpu, from\_gpu)
• Kernel management (use\_kernel, make\_prog, setarg, run\_kernel)
• Cleanup utilities to safely release OpenCL resources

Installation

Add OBRAH to your Cargo.toml:

\[dependencies]

obrah = "1.1.3"

OBRAH automatically includes OBWIO as a dependency.

Requirements

• Rust 1.70 or later
• OpenCL SDK installed on your system
• Compatible OpenCL runtime and drivers

Acknowledgments

OBRAH is built on OBWIO, which uses bindgen to generate FFI bindings. Thanks to the Rust and OpenCL communities for their documentation and support.
