  5. object Memo

    Permalink

    Memoizing different types of functions.

    Memoizing different types of functions.

    Calling a memoized function with a set of arguments for the first time will save the result in a cache - a mutable.Map, possibly user-provided. Calling it with the same set of arguments subsequently will not perform the computation, but retrieve the cached value instead.

    This is useful for computations that are expensive and are performed many times with the same arguments.

    However, functions need to be referentially transparent (i.e. have no side effects) to preserve correctness.

  6. object Monoids

    Permalink

    Missing instances of cats.Monoid.
