truce-gpu

wgpu rendering backend for the truce built-in GUI.

Overview

Provides WgpuBackend, a hardware-accelerated implementation of truce_gui_types::RenderBackend via wgpu (Metal on macOS, DX12 on Windows, Vulkan on Linux), plus the wgpu surface / swapchain glue. Uses lyon for path tessellation and fontdue for glyph atlas generation. Widgets render identically to the CPU path but with better performance on complex UIs.

truce-gpu is an implementation detail of truce-gui: the GpuEditor there wraps the built-in widget runtime and renders through this backend. Plugins don't depend on truce-gpu directly — they enable GPU rendering through truce-gui's gpu feature.

Key types

• WgpuBackend -- implements truce_gui_types::RenderBackend using wgpu

Usage

Opt into GPU rendering by enabling the gpu feature on truce-gui:

[dependencies]
truce     = { version = "0.48", features = ["clap"] }
truce-gui = { version = "0.48", features = ["gpu"] }

truce-gui pulls in truce-gpu transitively and routes the built-in editor through WgpuBackend. No direct dependency and no per-editor code: the same editor() impl works for both renderers.

fn editor(&self) -> Box<dyn Editor> {
    GridLayout::build(vec![widgets(vec![
        knob(P::Gain, "Gain"),
    ])])
    .into_editor(&self.params)
}
