//! A file table module for AbleOS
//!
//! This module provides a file table interface for AbleOS.
//!
//! # Examples
//! ```
//! use relib::filesystem::ProtoFileTable;
//! let mut file_table = ProtoFileTable::new();
//! file_table.add_file("test.txt", "Hello, world!".as_bytes());
//! let file = file_table.get_file("test.txt");
//! assert_eq!(file.unwrap().as_slice(), "Hello, world!".as_bytes());
//! ```
//! # Notes
//! The file table is a simple in-memory hashmap.
//! The file table is not thread safe.
//! The file table is not persistent.
