DepOnlyIncompatibleInfo

A provider for defining custom soft error categories for dep-only incompatible targets. This can be used to get finer-grained data on whether it is safe to enable error_on_dep_only_incompatible for a given target.

To use this, first define rule returning this provider.

def _impl(ctx: AnalysisContext) -> list[Provider]:
   return [
      DefaultInfo(),
      DepOnlyIncompatibleInfo(custom_soft_errors = {
         "dep_only_incompatible_foo": DepOnlyIncompatibleRollout(
            target_patterns = ["root//foo/..."],
            exclusions = ["root//foo/excluded/..."],
         ),
         "dep_only_incompatible_bar": DepOnlyIncompatibleRollout(
            target_patterns = ["root//bar/..."],
            exclusions = [],
         ),
      })
   ]

Then register a target of this rule in root .buckconfig under buck2.dep_only_incompatible_info buckconfig key. Once registered, soft errors will be fired under category "dep_only_incompatible_foo" when a target in root//foo/... is dep-only incompatible and likewise dep_only_incompatible_bar for a target in root//bar/....
