Module plumbing 

The implementation of the query system itself. This defines the macros that generate the actual methods on tcx which find and execute the provider, manage the caches, and so forth.

Macros

cycle_error_handling 🔒

Expands to one of two token trees, depending on whether the current query has the cache_on_disk_if modifier.

item_if_cache_on_disk 🔒

Conditionally expands to some token trees, if the current query has the cache_on_disk_if modifier.
