It's funny how these things are so personal. I love Godoc, mostly because everything is on one page, with very little JS and a good, almost monochrome colour palette. At the same time, I really can't stand Rust's docs, because everything seems to get its own page, it's colours galore, and of course there is a sidebar.
The mileage does vary greatly apparently.
See for example https://docs.rs/diesel/1.2.2/diesel/pg/index.html.
Godoc is too plain and almost cumbersome to read for me, while Elixir is too pretty and not so efficient in displaying the type information in my opinion.
Rust has a happy middle ground here.
