twig_sys/
lib.rs

1//! Low-level FFI bindings for Twig's C ABI, plus the build script that links
2//! the native `libtwig.a`.
3//!
4//! This crate is the `-sys` layer: it exposes the raw `extern "C"` functions,
5//! the `#[repr(C)]` type mirrors, and the status/format constants, and nothing
6//! else. The safe, ergonomic API lives in the `twig-doc` crate, which depends
7//! on this one. Direct use is `unsafe` and unstable across ABI-version bumps —
8//! see [`TWIG_ABI_VERSION`].

22// (the offsets are the LP64/LLP64 layout); 32-bit targets pack tighter but the
