General purpose global allocator(s) with static storage

static-alloc

General purpose global allocator(s) with static storage.

Goal and Target Platform

Provides an allocator for extremely resource constrained environments where the only memory guaranteed is your program's image in memory as provided by the loader. Possible use cases are OS-less development, embedded, bootloaders (even stage0/1 maybe, totally untested). The primary goals are minimalism, simplicity, and correctness.

This library is far from complete, and contributions with bug fixes or more allocators are welcome. As a general principle those should provide mechanisms, not policy, have a usable direct api that does not require them to be registered as the single global allocator.

Feature requests and 'help' issues will be closed, drafts will be decided on the spot. With simplicity in mind, ideas that can not be put into a draft form are likely too complex anyways. PRs should be extremely reluctant with introducing new dependencies and should contain no non-optional dependency.

Usage

use static_alloc::Slab;

#[global_allocator]
static A: Slab<[u8; 1 << 16]> = Slab::uninit();

fn main() {
    let v = vec![0xdeadbeef_u32; 128];
    println!("{:x?}", v);
}
