I have a JSON viewer/editor/formatter/validator in the form of Neovim, and it's been difficult to find one that can offer features that it can't. I use a terminal viewer which has been fairly ok in limited use-cases called `jsonfui`, but it too is written in Javascript, and while this will work for smaller JSON files, I want something for files in the megabytes to gigabytes range.

I have been on and off working on something in that style for the past few months that I wrote in Rust, but it seems that waiting for someone else to do it first isn't working, so I may have to just finish it myself.
