I’m considering if I should update my crates to require version 1.31 aka Rust 2018. That made me wonder if there is any statistics on the adoption rate of different Rust versions? That would in turn tell me how many users I would affect if I start requiring Rust 2018 as a baseline.
The Rust Survey 2018 asked people which version they used, and ~75% use the current stable version, with ~55% using the nightly version:
Does anybody know of any other statistics on this?
While crates.io publish download statistics for every crate, I don’t think there are numbers published for the
rustup downloads? If the downloads per
rustup channel is tracked, could they be made available? I think it would be an interesting signal for crate owners.
