This is awesome! I've been developing firmware in Rust for a Hall Effect keyboard (with springless, magnetic separation switches!) I'm developing/inventing (just ordered the first PCBs!). I really wish we had something similar in the embedded Rust ecosystem as a lot of the crates mentioned don't support #![no_std] (declaration you make at the top of your Rust code to indicate that the compiler should not include the standard library).

The world of embedded Rust seems to be developing incredibly fast. Especially since there's so much hardware that you can use with it now and more is on the way (especially in the world of RISC-V... Holy crap there's a lot of interesting and exciting hardware coming!). As a result of that I seem to be regularly encountering situations where I try to do something basic but no one has "made a crate for that yet" (that works with #![no_std]).

Just the other day I found out just how difficult it is to benchmark something (i.e. grab the current time, do something, get the time again, then subtract the difference... It's really, really complicated! Way moreso than it should be). If someone wanted to make a name for themselves by developing widely-used software now is the time to make your mark! The world of embedded Rust is waiting for you!

FYI: I'm still a newbie when it comes to Rust but I was able to develop a universal driver (works with any hardware platform) for working with 74HC4067 and 74HC4051 analog multiplexers in just a few days... https://crates.io/crates/analog-multiplexer
