Welcome to Space Age on Exercism's Rust Track.
If you need help running the tests or submitting your code, check out HELP.md

Given an age in seconds, calculate how old someone would be on:
So if you were told someone were 1,000,000,000 seconds old, you should be able to say that they're 31.69 Earth-years old.
If you're wondering why Pluto didn't make the cut, go watch this youtube video.
Some Rust topics you may want to read about while solving this problem:
Traits, both the From trait and implementing your own traits
Default method implementations for traits
Macros, the use of a macro could reduce boilerplate and increase readability
for this exercise. For instance,
a macro can implement a trait for multiple types at once,
though it is fine to implement years_during
in the Planet trait itself. A macro could
define both the structs and their implementations. Info to get started with macros can
be found at:
