While we have curated lists for everything in Rust I thought that if it was great to have documentation of various things of the language organized in another fashion, rather than the lists (obviously not detracting them).
Also I was thinking the idea of having the option of converting documentation to PDF form and adding Rust documentation in other languages .
I think you're describing something like an Are We Web Yet? curated list of interesting docs in the Rust ecosystem. I especially like the goal of including static downloads and encouraging better language support.
Potentially worth noting - mdbook (the standard tool for Rust prose documentation) has an experimental epub exporter: https://crates.io/crates/mdbook-epub
