## What it is
A Rust library providing generic caching structures (LRU, Redis, disk-backed stores) and macros for easy function memoization. It supports both synchronous and asynchronous memoized functions with configurable write synchronization.

## Use cases
- memoize expensive function calls in Rust
- add an LRU cache to my Rust application
- cache function results across processes with Redis
- cache results to disk in Rust
- memoize async functions
- avoid recomputing results for repeated arguments

## When to choose
- you need drop-in function memoization in Rust with a macro
- you want multiple backing stores (in-memory, Redis, disk) behind one API
- you need thread-safe caching with configurable concurrency semantics

## When to avoid
- you need a distributed cache cluster rather than a client library
- you want a language-agnostic caching proxy like Redis or Memcached itself
- your project must compile on Rust versions older than 1.92

## Facets
- artifact type: library
- maturity: stable
- function: caching
- domain: developer-tools, performance
