> This is probably related to Rust's unability to support hash for f32 and f64, as `Eq` is still not stabilized for them (and Hash and Eq must be consistent). @houqp found an issue https://github.com/tkaitchuck/aHash/issues/93 in upstream (trying to hash an `usize`). I think it could be solved easily there by casting it to `u64`. It's not totally clear to me what's the difference between nightly and stable. -- This is an automated message from the Apache Git Service.
