truce_gpu/lib.rs
1//! GPU rendering backend for truce plugins.
2//!
3//! Uses wgpu (Metal/DX12 backends per the workspace's feature pin) with
4//! lyon tessellation and a fontdue glyph atlas. Implements
5//! `truce_gui::RenderBackend` so widgets render identically to the CPU
6//! path.
7//!
8//! Platform windowing is provided by baseview.

10/// Crate-wide debug-print macro for GPU init / render hot-reload paths.
11/// Compiles to nothing unless the `hot-debug` feature is enabled.
12/// Defined at crate root so any module under `truce_gpu::*` can reach
13/// it without re-importing.
