monagement 0.0.2

About

Monagement, is a memory allocator project written in rust that is based on the TLSF (Two-Level Segregated Fit) concept.

Main Architecture

Two-Level Segregated Fit

uses a 2-level bitmap hierarchy in searching for empty blocks, thus reducing the need for linear scanning.

Bitmap

use of bitmaps for fast search

Coalescing

any adjacent free blocks will be automatically merged to reduce fragmentation.

Or add the following line to your Cargo.toml:

monagement = "0.0.2"

Code

use monagement::{Monagement, MonagementInit};
use std::num::NonZeroU64;

fn main() {
    let allocator = Monagement::init(MonagementInit::default()).expect("Monagement Init Error");

    // allocate memory
    let allocate_a = allocator
        .allocate(NonZeroU64::new(12).unwrap())
        .expect("Memory Allocation A Error");
    let allocate_b = allocator
        .allocate(NonZeroU64::new(20).unwrap())
        .expect("Memory Allocation B Error");

    // free up memory
    allocate_a.free();
    // or
    drop(allocate_b);

    // get data link memory
    println!("{:#?}", allocator.borrow_core().get_linked_list());
