# Include the Generated Bindings in `src/lib.rs`
We can use the `include!` macro to dump our generated bindings right into our
crate's main entry point, `src/lib.rs`:
```rust,ignore
#![allow(non_upper_case_globals)]
#![allow(non_camel_case_types)]
#![allow(non_snake_case)]
include!(concat!(env!("OUT_DIR"), "/bindings.rs"));
```
Because `bzip2`'s symbols do not follow Rust's style conventions, we suppress a
bunch of warnings with a few `#![allow(...)]` pragmas.
We can run `cargo build` again to check that the bindings themselves compile:
```bash
$ cargo build
Compiling bindgen-tutorial-bzip2-sys v0.1.0
Finished debug [unoptimized + debuginfo] target(s) in 62.8 secs
```
And we can run `cargo test` to verify that the layout, size, and alignment of
our generated Rust FFI structs match what `bindgen` thinks they should be:
```bash
$ cargo test
Compiling bindgen-tutorial-bzip2-sys v0.1.0
Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs
