I actually contributed quite a bit to a fork of godit called vigo [0]. It gave me lots of insight into how text editors work.
When I went to start writing Iota, I found that there was no termbox-type library in Rust, so I created a wrapper [1]. My goal is to create a pure-Rust version, similar to termbox-go. It's a long way from that, but it will get there!
I initially found it much harder to work with Rust, as the language is more strict in a number of ways. But once I began to understand how it works, and began to grasp some of its concepts such as ownership and lifetimes I found it much more powerful than Go.
Go has a larger community right now, many more libraries and resources openly available. That's probably one of Rust's downsides right now however its catching up, especially with the launch of crates.io. I don't think it will be long in maturing following the 1.0 release.
Saying that, both are enjoyable to work with. But for me Rust wins out!
