embedded-3dgfx 0.7.1

//! Pipeline stage 5 — output.
//!
//! Framebuffer backends ([`display_backend`]), triple-buffered presentation
//! ([`swapchain`]), async DMA completion slots ([`completion`]), and the 2D
//! [`hud`] overlay composited over the rendered frame.
//!
//! # Writing a display backend
//!
//! The traits below name types from `embedded-graphics-framebuf` in their
//! signatures, so they are re-exported here: a driver needs exactly one `use`:
//!
//! ```
//! use embedded_3dgfx::pipeline::output::{
//!     DisplayBackend, DisplayRegion, DmaTransfer, FrameBuf, StandardSwapChain, TransferError,
//! };
//! ```

// submodules stay minimal — this is the deliberate, curated surface for the
