crates.io build fail on Rust Nightly

[k-stanislawek]

Latest version published to crates.io (0.3.3) fails build on today's & yesterday's (2020-10-04 & 03) nightly. It can be checked by building a sample project that has dependency on it. Or like this:

We cannot publish another version to the packed_simd crate itself. We lack the crates.io permissions. The original maintainer is out of contact.

If you adjust your dependency entry like this it should pick up the crate we published under an alternative name, which should build.

packed_simd = { version = "0.3.4", package = "packed_simd_2" }

Thanks! I've solved my problem: It was a transitive dependency Parquet, but its latest version was already fixed.

[k-stanislawek]

I'd suggest adding a note to the readme.md.

[Lokathor]

yep, just been quite busy lately. opened https://github.com/rust-lang/packed_simd/pull/305
