Blade is a low-level GPU library in Rust with the focus on ergonomics. It's unsafe, it's incomprehensive, but it's small, fast, and actually fun to prototype with!

See motivation, FAQ, and performance for more info.

The backend is selected automatically based on the host platform.

Vulkan:

• Desktop Linux/Windows
• Android

Metal:

• Desktop macOS
• iOS

OpenGL ES:

• Web

Check:

cargo check

Run the minimal example:

cargo run --example mini

GLES is also supported at a basic level. It's enabled for wasm32-unknown-unknown target, and can also be force-enabled on native:

RUSTFLAGS="--cfg gles" CARGO_TARGET_DIR=./target-gl cargo test

This path can be activated on all platforms via Angle library. For example, on macOS it's sufficient to place libEGL.dylib and libGLESv2.dylib in the working directory.

Following command will start a web server offering the bunnymark example:

cargo run-wasm --example bunnymark

First, ensure to load the environment from the Vulkan SDK:

cd /opt/VulkanSDK && source setup-env.sh

Vulkan backend can be forced on using "vulkan" config flag. Example invocation that produces a vulkan (portability) build into another target folder:

RUSTFLAGS="--cfg vulkan" CARGO_TARGET_DIR=./target-vk cargo test
