| /// libminijail bindings for Rust. |
| |
| // TODO(crbug.com/1032672): Generate bindings at build time. |
| // |
| // Bindgen will invoke the C preprocessor to process headers, which means that the bindings |
| // generated can depend on the architecture that actually ran bindgen. In particular, for |
| // portability across compilers glibc defines types like __u8 and __rlim64_t in terms of C types |
| // like unsigned char and unsigned long. This is problematic for __rlim64_t since that resolves to |
| // unsigned long int on amd64, which will end up being 32-bit on 32-bit platforms. |
| // |
| // As a workaround to let us commit these bindings and still use them on 32-bit platforms, the |
| // bindgen invocation blacklists some of the generated fixed-width types and redefines them |
| // manually as Rust fixed-width types. |
| // |
| // Generated in CrOS SDK chroot with: |
| // bindgen --default-enum-style rust \ |
| // --blacklist-type '__rlim64_t' \ |
| // --raw-line 'pub type __rlim64_t = u64;' \ |
| // --blacklist-type '__u\d{1,2}' \ |
| // --raw-line 'pub type __u8 = u8;' \ |
| // --raw-line 'pub type __u16 = u16;' \ |
| // --raw-line 'pub type __u32 = u32;' \ |
| // --blacklist-type '__uint64_t' \ |
| // --whitelist-function '^minijail_.*' \ |
| // --whitelist-var '^MINIJAIL_.*' \ |
| // --no-layout-tests \ |
| // --output libminijail.rs \ |
| // libminijail.h -- \ |
| // -DUSE_BINDGEN \ |
| // -D_FILE_OFFSET_BITS=64 \ |
| // -D_LARGEFILE_SOURCE \ |
| // -D_LARGEFILE64_SOURCE |
| // |
| // Enum variants in rust are customarily camel case, but bindgen will leave the original names |
| // intact. |
