/* * `bindgen` binds the C `size_t` type as the Rust `usize` type, so we can * use it in contexts where Rust expects a `usize` like slice (array) indices. * `usize` is defined to be the same as C's `uintptr_t` type (can hold any * pointer) but not necessarily the same as `size_t` (can hold the size of any * single object). Most modern platforms use the same concrete integer type for * both of them, but in case we find ourselves on a platform where * that's not true, fail early instead of risking ABI or * integer-overflow issues. * * If your platform fails this assertion, it means that you are in * danger of integer-overflow bugs (even if you attempt to add * `--no-size_t-is-usize`). It may be easiest to change the kernel ABI on * your platform such that `size_t` matches `uintptr_t` (i.e., to increase * `size_t`, because `uintptr_t` has to be at least as big as `size_t`). */static_assert( sizeof(size_t) == sizeof(uintptr_t) && __alignof__(size_t) == __alignof__(uintptr_t), "Rust code expects C `size_t` to match Rust `usize`");
