Innovation, oh my, sometimes it feels like the fat ones (and, by proxy, everyone else) are living in some alternate fantasy world where the mantra "you're not gonna need it" is taken to the extreme, so they're not even trying.
The pendulum should swing back to complex and more complicated interfaces sometime — but right now these are the dark times where, for example, Netflix, this huge, popular movie and show library, doesn't even have a way to find out exactly what movies with some actor or director it has available. It's hard for me to wrap my head around that.
Your project does look useful and on point though!
What does one do if they wish to see the actual contents of this crate? The web interface I'm looking at contains no hints at peeking inside, not even direct archive download links, nothing.
I can't believe that a good way to see what's inside is to make a rust project, add the crate and then go searching around the local filesystem.
From programming perspective, there's nothing sufficiently preposterous in the idea of dividing by zero that would require bringing the whole world to a low-level halt just for attempting that by default. You tried to calculate the average value of what turned out to be an empty list? Go suffer the most severe exception, like the ones reserved for those reading from nonexistant memory.
