1# Include the Generated Bindings in `src/lib.rs` 2 3We can use the `include!` macro to dump our generated bindings right into our 4crate's main entry point, `src/lib.rs`: 5 6```rust,ignore 7#![allow(non_upper_case_globals)] 8#![allow(non_camel_case_types)] 9#![allow(non_snake_case)] 10 11include!(concat!(env!("OUT_DIR"), "/bindings.rs")); 12``` 13 14Because `bzip2`'s symbols do not follow Rust's style conventions, we suppress a 15bunch of warnings with a few `#![allow(...)]` pragmas. 16 17We can run `cargo build` again to check that the bindings themselves compile: 18 19```bash 20$ cargo build 21 Compiling bindgen-tutorial-bzip2-sys v0.1.0 22 Finished debug [unoptimized + debuginfo] target(s) in 62.8 secs 23``` 24 25And we can run `cargo test` to verify that the layout, size, and alignment of 26our generated Rust FFI structs match what `bindgen` thinks they should be: 27 28```bash 29$ cargo test 30 Compiling bindgen-tutorial-bzip2-sys v0.1.0 31 Finished debug [unoptimized + debuginfo] target(s) in 0.0 secs 32 Running target/debug/deps/bzip2_sys-10413fc2af207810 33 34running 14 tests 35test bindgen_test_layout___darwin_pthread_handler_rec ... ok 36test bindgen_test_layout___sFILE ... ok 37test bindgen_test_layout___sbuf ... ok 38test bindgen_test_layout__bindgen_ty_1 ... ok 39test bindgen_test_layout__bindgen_ty_2 ... ok 40test bindgen_test_layout__opaque_pthread_attr_t ... ok 41test bindgen_test_layout__opaque_pthread_cond_t ... ok 42test bindgen_test_layout__opaque_pthread_mutex_t ... ok 43test bindgen_test_layout__opaque_pthread_condattr_t ... ok 44test bindgen_test_layout__opaque_pthread_mutexattr_t ... ok 45test bindgen_test_layout__opaque_pthread_once_t ... ok 46test bindgen_test_layout__opaque_pthread_rwlock_t ... ok 47test bindgen_test_layout__opaque_pthread_rwlockattr_t ... ok 48test bindgen_test_layout__opaque_pthread_t ... ok 49 50test result: ok. 14 passed; 0 failed; 0 ignored; 0 measured 51 52 Doc-tests bindgen-tutorial-bzip2-sys 53 54running 0 tests 55 56test result: ok. 0 passed; 0 failed; 0 ignored; 0 measured 57``` 58
