Functions
Install a caching-wrapped executor for a single contract.
Shorthand for with_cached_executors/2.
Install caching-wrapped executors for multiple contracts. Initialises a scoped cache and wraps executors so identical queries return cached results without re-executing.
Install an executor module for a single query contract.
Install executor modules for multiple query contracts.
Accepts either a list of {contract_module, executor_module} tuples or a map.

@spec with_executor(Skuld.Comp.Types.computation(), module(), module()) :: Skuld.Comp.Types.computation()
Install an executor module for a single query contract.
The executor module must implement the contract's callbacks.
Install executor modules for multiple query contracts.
Accepts either a list of {contract_module, executor_module} tuples or a map.
