Function nova_rt_fs_create_dir_all 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nova_rt_fs_create_dir_all(
    path: *const NovaStr,
) -> i64

Create the directory path, and any missing parent directories along the way. Unlike create_dir, an existing directory at path is success, not ALREADY_EXISTS – std::fs::create_dir_all’s own behaviour, carried through unchanged rather than papered over.

Safety

path must point to a live NovaStr.
