Rust bindings for AMD's DirectX12 RGP markers

Call AMD's command list markers directly in Rust for event instrumentation in [Radeon GPU Profiler], as well as other functionality provided on IAmdExtD3DDevice1.

Usage

Add this to your Cargo.toml:

toml [dependencies] amd-ext-d3d = "0.1.0"

While [upstream documentation] details how to embed these calls into existing PIX3 markers (behind a C #derive), you get to call them explicitly in Rust:

```rust,norun use amdext_d3d::AmdExtD3DDevice; use std::ffi::CStr; use windows::core::CanInto; use windows::Win32::Graphics::Direct3D12::{ID3D12Device, ID3D12GraphicsCommandList};

let device: ID3D12Device = todo!("Open DirectX12 graphics device"); let cmd_list: ID3D12GraphicsCommandList = todo!("device.CreateCommandList(...)");

// Load the extension let amddevice = unsafe { AmdExtD3DDevice::new(device.canclone_into()) }.unwrap();

let name = CStr::frombyteswithnul(b"My super cool GPU event!\0").unwrap(); unsafe { amddevice.pushmarker(&cmdlist, name) }; // Submit work to the GPU... unsafe { amddevice.popmarker(&cmd_list) }; ```
