# nix-bindings-expr-sys This crate contains generated bindings for the Nix C API (`nix-expr-c`). **You should not have to use this crate directly,** and so you should probably not add it to your dependencies. Instead, use the `nix-bindings-expr` crate, which _should_ be sufficient. [API Documentation](https://nixops4.github.io/nix-bindings-rust/development/nix_bindings_expr_sys/) ## Changelog See the [nix-bindings-rust changelog](https://github.com/nixops4/nix-bindings-rust/blob/main/CHANGELOG.md).
