4//! Low-level FFI bindings for the TensorFlow Lite C API.
5//!
6//! This crate provides raw, unsafe bindings generated by `bindgen` with
7//! `--dynamic-loading`. Symbols are resolved at runtime via `libloading`.
8//!
9//! **Most users should depend on `edgefirst-tflite` instead**, which
10//! provides a safe, ergonomic API on top of these bindings.
11//!
12//! # Library Discovery
13//!
14//! Use [`discovery::discover`] to automatically find and load the `TFLite`
15//! shared library, or [`discovery::load`] to load from a specific path.
16//!
17//! # Delegate Extensions
18//!
19//! The [`hal_ffi`] module provides function pointer structs for the
20//! HAL Delegate DMA-BUF API (the standard, delegate-agnostic interface).
21//!
22//! The [`vx_ffi`] module provides function pointer structs for the
23//! legacy `VxDelegate` DMA-BUF and `CameraAdaptor` APIs. Both are loaded
24//! at runtime from the delegate shared library.
