range-alloc-arceos

range-alloc-arceos is a generic range allocator tailored for the ArceOS ecosystem.

It is a fork of the excellent 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.

Usage

Add this to your Cargo.toml:

[dependencies]
range-alloc-arceos = "0.1.0-alpha.1"

Example

use range_alloc_arceos::RangeAllocator;

fn main() {
    // Initialize the allocator with a range (e.g., 0..100)
    let mut allocator = RangeAllocator::new(0..100);

}
