I’m writing a custom rule in Skylark, and in the rule I would like to access the current toolchain action definitions that were created via cc_common.create_cc_toolchain_config_info(), essentially the contents of the action_configs argument. Is there any way to do this within a custom rule?

I would imagine that an aspect could do this, but I suspect for my use case it would create a circular dependency. I’m interested in the action definition for the current C++ toolchain independent of a given target.

I tried cc_common.get_tool_for_action(), but it is unhelpful as there can be an action defined for a tool without an associated make variable, they are configured separately and what I need is in CcToolchainConfigInfo.
