//! inode based
//!
//! it is not recommend to use this inode based [`Filesystem`] first, you need to handle inode
//! allocate, recycle and sometimes map to the path, [`PathFilesystem`][crate::path::PathFilesystem]
//! helps you do those jobs so you can pay more attention to your filesystem design. However if you
//! want to control the inode or do the path<->inode map on yourself, [`Filesystem`] is the only one
//! choose.
