Crate ruspiro_allocator[][src]

Custom Allocator for HEAP memory allocations

This crate provides a custom allocator for heap memory. If any baremetal crate uses functions and structures from the alloc crate an allocator need to be provided as well. However, this crate does not export any public API to be used. It only encapsulates the memeory allocator that shall be linked into the binary.


The lock free memory allocations use atomic operations. Thus to properly work on a Raspberry Pi the MMU is required to be configured and enabled. Otherwise memory allocations will just hang the cores.


To link the custom allocator with your project just add the usage to your main crate rust file like so:

extern crate ruspiro_allocator;

Wherever you define the usage of the ruspiro-allocator crate within your project does not matter. But as soon as this is done the dynamic structures requiring heap memory allocations from the alloc crate could be used like so:

extern crate alloc;
use alloc::{boxed::Box, vec::Vec};

fn main() {
    let mut v: Vec<u32> = vec![10, 20];
    let b: Box<u16> = Box::new(10);
