truce-gpu

GPU rendering backend for truce plugins.

Overview

Wraps the built-in widget toolkit from truce-gui with hardware-accelerated rendering via wgpu (Metal on macOS, DX12 on Windows, Vulkan on Linux). Uses lyon for path tessellation and fontdue for glyph atlas generation. Platform windowing is provided by baseview. Widgets render identically to the CPU path but with significantly better performance on complex UIs.

User plugins take a direct dep on this crate (truce-gpu = { workspace = true }) when they want a GPU-rendered editor. Every in-tree example plugin uses this path.

Key types

• GpuEditor -- GPU-accelerated Editor implementation
• WgpuBackend -- implements truce_gui::RenderBackend using wgpu

Usage

[dependencies]
truce     = { git = "https://github.com/truce-audio/truce", tag = "vX.Y.Z", features = ["clap"] }
truce-gpu = { git = "https://github.com/truce-audio/truce", tag = "vX.Y.Z" }

(Replace vX.Y.Z with the latest release tag from the releases page, or run cargo truce new and let the scaffolder pin for you.)
