Description

For embedded devices it would be great if we can use a no-std environment and meaningful subsets for stuff that is not part of the no-std create such as RefCells, HashMaps and others.

see // FIXME no-std

Contributor guide

Research direction
Identify all std dependent code marked with `// FIXME no std` and replace with core/alloc alternatives. Ensure conditional compilation using `#![cfg attr(not(feature="std"), no std)]`.
