Fails to build on the latest nightly when using the nightly feature #15
Description
Hi, thanks for your work on this useful library! 😄
As stated in the issue title, simd-adler32 fails to build on the latest nightly (rustc 1.78.0-nightly (d44e3b95c 2024-02-09)) due to an unstable feature that was removed:
This is a fairly recent regression: nightlies older than a week or so are unaffected.
The Rust tracking issue for the removed stdsimd feature has already been referenced by other affected projects: rust-lang/rust#48556
