provide with_platform_verifier_and_extra_roots extension function

[conradludgate]

Fixes #202

[djc]

No extra roots on Android... maybe an extension trait method that yields some kind of builder which only offers to set extra roots on non-Android?

[conradludgate]

The android/ios tests failing seems to be unrelated. The semver error is correct, but I feel like it is not significant here - no one should be using dyn BuilderVerifierExt.

This looks good to me. I agree the technical semver breakage shouldn't be important. I have a really hard time seeing anyone using the extension traits in their own type declarations since there's only one implementation of each anyway.

I assume if we merge this the cargo-semver-checks job will start to ignore this past "breakage" on future PRs and go back to being green?

[djc]

Probably only after we release.

[complexspaces]

Should we go ahead and merge this and then release next week? We have enough changes in main to make a new one IMO.

[djc]

Sounds good to me.
