litert-sys

Raw FFI bindings to Google's LiteRT 2.x C API.

This is the unsafe FFI layer — most users want the safe wrappers in the litert crate instead. Pre-generated bindings ship for every supported target so no libclang is required on end-user machines.

At build time, litert-sys/build.rs downloads the pinned LiteRT prebuilt shared libraries (Google Git LFS for desktop, Google Maven AAR for Android), SHA-256-verifies them against in-crate checksums, and caches them under $XDG_CACHE_HOME/litert-sys/. Every target flows through one pure-Rust download path — no CMake, no Bazel, no shell scripts.

See the workspace README for the full feature matrix, platform support, and contributor guide.
