Project

This repository contains code for verified storage systems. The code is written in, and its correctness properties are verified with, Verus.

This project contains the following crates:

  • pmemlog implements an append-only log on persistent memory. The implementation handles crash consistency, ensuring that even if the process or machine crashes, it acts like an append-only log across the crashes. It also handles bit corruption, detecting if metadata read from persistent memory is corrupted.
  • storage_node is an in-progress persistent memory key-value store. Its structure is further described in its README.
  • unverified contains unverified mocks and tests related to the storage_node key value store.
  • deps_hack contains unverified dependencies that are imported by storage_node.
