fix build failure caused by `stdsimd` feature #724

Closed wangkirin closed 5 months ago

wangkirin commented 5 months ago

I try to build a crater service in our CI pipeline, and when I try to compile crater, error occurs:

error[E0635]: unknown feature `stdsimd`
  --> /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/ahash-0.8.6/src/lib.rs:99:42
   |

   |                                          ^^^^^^^

For more information about this error, try `rustc --explain E0635`.
error: could not compile `ahash` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...

my rust verion is 

rustc 1.78.0-nightly (3cbb93223 2024-03-13)
``` ,

I think this failure is caused by  the remove of `stdsimd` feature and the `ahash` package has already updated to fix it : https://github.com/tkaitchuck/aHash/pull/183

I run `cargo update -p ahash` to slove this and seems `crc32c`  has the similar problem

after I run `cargo update -p crc32c`, the complie process is OK

this PR update the Cargo.lock to fix this issue
