affineui_sys/
lib.rs

1//! Raw FFI bindings to the AffineUI C ABI.
2//!
3//! Hand-written against `include/affineui/c_api.h` and
4//! `include/affineui/c_api_app.h` (docs/LANGUAGE_BINDINGS.md §4.1 explains
5//! why these are hand-written rather than bindgen-generated). Names, enum
6//! values, and struct layouts mirror the headers exactly; the headers are
7//! the source of truth and the C ABI version gate
8//! ([`affineui_c_abi_version`]) protects against drift at load time.
9//!
10//! Everything here is `unsafe` and 1:1; use the `affineui` crate for the
11//! safe, idiomatic surface.
