v8.0.0: Re-write for the next version

[CraZySacX]

Release 8.0.0-beta.0 has been published

crates.io
docs.rs

Feel free to comment on this PR about the main goals outline below

• Minimize the vergen footprint.
  • Adopt an opt-in methodology rather than opt-out.
  • Move from _mut config to a builder pattern.
  • Default features empty
  • Support the ability to configure vergen to emit warnings rather than a hard build error.
• Minimize the vergen compile time impact.
  • git2 is a large feature, add back support for command line git to help here.
  • Remove extraneous libraries that add fluff over functionality, i.e. thiserror
• Allow for idempotent output.
  • There have been requests to force vergen output to be reproducible. See Read environment variables to remove impurities #141 for more information on this.
  • Support environment variables like SOURCE_DATE_EPOCH that make reproducible easier.
  • Backport this to v7 and maybe v6?
• vergen should compile and test from a source tarball
  • A missing .git directory is the current culprit here.
  • Backport this to v7 and maybe v6?

Hey @CraZySacX,

Thank you very much for vergen we use it in Meilisearch and it works great! However, I was trying to update our dependencies to enum-iterator and was unable to bump to the 1.2.0 one, we are stuck using 1.1.3. Is there a particular reason why you depend on ~1.1.3 and not upgrading to the new version?

Thank you

Thank you

The original reason was #132. I'll check version 1.2.0 to see if they have removed that nightly only dependency.

Ho right! I understand. It has been shipped in stable since 1.63, now.

Yep, seem good on stable now. I'll push out a new v7 release here shortly.

@Kerollmops I've pushed out 7.5.0. Had to bump the MSRV to 1.63 as well.
