Abstract base class for memory in LangChain's Chains. Memory refers to the state in Chains. It can be used to store information about past executions of a Chain and inject that information into the inputs of future executions of the Chain.

Abstract method that should take an object of input values and return a Promise that resolves with an object of memory variables. The implementation of this method should load the memory variables from the provided input values.

Abstract method that should take two objects, one of input values and one of output values, and return a Promise that resolves when the context has been saved. The implementation of this method should save the context based on the provided input and output values.
