MSRV on `digest` v0.10.4 is broken

[striezel]

When trying to build a project that depends on digest v0.10.4 with rustc 1.48, one gets error messages from cargo. This appears to be a similar issue like e. g. RustCrypto/hashes#398 and probably needs a similar fix like RustCrypto/hashes#401.

The error message is:

error: failed to parse manifest at `/root/.cargo/registry/src/github.com-1ecc6299db9ec823/digest-0.10.4/Cargo.toml`

Caused by:
  feature `resolver` is required

  this Cargo does not support nightly features, but if you
  switch to nightly channel you can add
  `cargo-features = ["resolver"]` to enable this feature

The problem is due to the generated Cargo.toml containing the resolver = "2" line: https://docs.rs/crate/digest/0.10.4/source/Cargo.toml

Since the documented MSRV of digest is still rustc 1.41, this breaks the MSRV guarantee.

Argh... This error again. I will do release fix right away. Thank you for monitoring it!

Thank you for monitoring it!

I am not actively monitoring it - even if it may look like it so soon after the release. I just happened to update the dependencies of one of my projects ca. 30 minutes ago, and that's where I hit that error.

digest v0.10.5 is published. Can you verify that it fixes the issue?

[striezel]

Yes, digest v0.10.5 can be compiled with rustc 1.48. So I consider this to be fixed.
