umm-malloc-rs

Provides a global allocator using the umm_malloc library.

umm_malloc is a small and simple malloc designed for embedded systems. It is able to allocate and free quickly with limited memory fragmentation.

Limitations

All allocations form this allocator are aligned by 8 bytes. Requesting a larger alignment is not implemented and will panic.

Future Work

umm_malloc has features for collecting metrics and detecting heap corruption, which could be exposed conveniently with cargo features.

An implementation of memalign could be added to umm_malloc.
