1//! [ArceOS](https://github.com/arceos-org/arceos) filesystem module.
2//!
3//! It provides unified filesystem operations for various filesystems.
4//!
5//! # Cargo Features
6//!
7//! - `fatfs`: Use [FAT] as the main filesystem and mount it on `/`. This feature
8//!   is **enabled** by default.
9//! - `devfs`: Mount [`axfs_devfs::DeviceFileSystem`] on `/dev`. This feature is
10//!   **enabled** by default.
11//! - `ramfs`: Mount [`axfs_ramfs::RamFileSystem`] on `/tmp`. This feature is
12//!   **enabled** by default.
13//! - `myfs`: Allow users to define their custom filesystems to override the
14//!   default. In this case, [`MyFileSystemIf`] is required to be implemented
15//!   to create and initialize other filesystems. This feature is **disabled** by
16//!   by default, but it will override other filesystem selection features if
17//!   both are enabled.
18//!
