Function fs_stat 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn fs_stat(
    handle: *mut FsHandle,
    name: *const c_char,
    out_size: *mut u64,
    out_kind: *mut i32,
    out_inode_id: *mut u64,
) -> i32

Stat metadata for a single file/directory.

Returns 0 on success and populates the out-parameters. Much cheaper than fs_list_dir for FUSE getattr / lookup.

out_size: file size in bytes (or 0 for directories). out_kind: 0 = file, 1 = directory. out_inode_id: the logical inode id.

Safety

handle, name, and all out_* pointers must be valid.
