# NVTX [](https://crates.io/crates/nvtx) [](https://docs.rs/nvtx) [](https://github.com/simbleau/nvtx/actions/workflows/build.yml) [](https://deps.rs/repo/github/simbleau/nvtx) A safe and ergonomic `#![no_std]` crate to bind the NVIDIA® Tools Extension SDK (NVTX) with zero-cost abstraction. NVIDIA® Tools Extension SDK (NVTX) is a C-based Application Programming Interface (API) for annotating events, code ranges, and resources in your applications. Official documentation for NVIDIA®'s NVTX can be found [here](https://nvidia.github.io/NVTX/doxygen/index.html). This library is a wrapper over that SDK, safely, and with zero-cost abstractions. This library facilitates integration into the rich CPU and GPU profiling tools provided by NVIDIA®, such as NSight Systems. The primary motivation for this library is to assist research GPU analysts and bring NVIDIA® tools to Rust. This crate is `#![no_std]`. # ➡️ Quickstart The crate is published on [crates.io](https://crates.io/crates/nvtx) and the easiest way to use nvtx is by adding the dependency to your `Cargo.toml` file: ```toml nvtx = "1.1.1" ```  There are several examples in the [`examples`](examples) folder which can be executed through tools such as NSight Systems. Each example has a README document with easy to read steps, screenshots, and documentation. Check out the first example, '[Hello, World!](https://github.com/simbleau/nvtx/tree/main/examples/hello_world)' 🙋 *If you need support, please [file an issue](https://github.com/simbleau/nvtx/issues/new) or [start a discussion](https://github.com/simbleau/nvtx/discussions/new).* --- ## 🤝 Contributing If you support the project, consider [sponsoring](https://github.com/sponsors/simbleau) or [buying a coffee](https://www.buymeacoffee.com/simbleau).
