The common general versions of memoized decorators ([1], [2], [3]) are
often good enough but they incur some overhead that can be avoided in more
special cases ([4]). This package exposes a single callable, memoized,
that picks an efficient memoization implementation based on the decorated
function's signature and a few user provided options. The included benchmark
file gives an idea of the performance characteristics of the different possible
implementations.
Additionally, memoized allows:
- Creating signature preserving decorators (through the decorator module).
- Passing an external object as the underlying storage (e.g. an LRU cache) instead of a dict that is used by default.
More options for customization and optimization may be added in the future.
