Usage in Embedded Systems

[Simsys]

This is a very nice compact library. You could use it wonderfully in embedded environments. You would need to be able to use it without importing the std library (no_std).

This is a feature request

I'd be interested in this as well :slightly_smiling_face:

I noticed that a big thing that is used from std which is not in core is the io::Result. Are there reasons to use that error type or could also a custom result / error type be used?
