Looking at wireguard-rs, in its current form it makes a lot of use of
`alloc` (namely `Vec` and `HashMap`) and `std` features (`fs`, `net`,
`sync`).

Getting it working on a Cortex-M would involve extracting a core protocol
implementation which doesn't make use of any of those features as a
library/crate which has no dependencies (or only optional dependencies
which can be switched off with Cargo features) on `alloc` and `std`.

(as it were, I'm also interested in using wireguard-rs this way in a
"heapless" no_std environment)
