memoize
A memoization macro for Elixir that caches function results using CAS on ETS for performance optimization.
What is memoize?
Memoize is an Elixir library that provides a `defmemo` macro to easily add memoization to functions, caching the results of expensive calls to avoid redundant computations and speed up programs. It leverages Erlang's ETS with CAS operations for thread-safe, efficient caching and offers features like exclusive execution to prevent parallel calls and flexible cache invalidation.
Elixir developers working on applications with computationally expensive or frequently called functions where caching results can significantly improve performance, such as those implementing recursive algorithms, external API calls, or data transformation pipelines.
Developers choose Memoize for its simplicity—replacing `def` with `defmemo` after `use Memoize`—and its robust features like exclusive execution to ensure correctness, configurable cache strategies including expiration and eviction, and the ability to implement custom caching behaviors via the `Memoize.CacheStrategy` protocol.
