Store: Snapshottable Data Structures

Store is a library to add snapshotting capabilities to imperative data structure with a low runtime cost and safe, user-friendly APIs. It is designed for (and works best with) applications that exploit backtracking algorithms, such as SMT solvers, type-checking and type-inference algorithms.

Currently, Store only provides snapshottable references; support for custom built-in data structures that benefit from non-backtracked operations (such as resizing a dynamic array) is planned.

The design of the Store library is described in the ICFP'24 paper:
