-**range-alloc-arceos** is a generic range allocator tailored for the ArceOS ecosystem. 
-
-It is a fork of the excellent [gfx-rs/range-alloc](https://github.com/gfx-rs/range-alloc), adapted for use in kernel development and embedded scenarios (`no_std`). It allows you to dynamically allocate and free ranges from a predefined memory block or address space.

-## Features
-
 - **`no_std` Support**: Designed for bare-metal and kernel environments.
 - **Generic**: Works with any type that satisfies the `Range` requirements (e.g., memory addresses, port numbers).
 - **Efficient**: Merges adjacent free ranges to minimize fragmentation.
