Module persist

When in incremental mode, this pass dumps out the dependency graph into the given directory. At the same time, it also hashes the various HIR nodes.

Modules

• data 🔒
  The data that we will serialize and deserialize.
• dirty_clean 🔒
  Debugging code to test fingerprints computed for query results. For each node marked with #[rustc_clean] we will compare the fingerprint from the current and from the previous compilation session as appropriate:
• file_format 🔒
  This module defines a generic file format that allows to check if a given file generated by incremental compilation was generated by a compatible compiler version. This file format is used for the on-disk version of the dependency graph and the exported metadata hashes.
• fs 🔒
  This module manages how the incremental compilation cache is represented in the file system.
• load 🔒
  Code to load the dep-graph from files.
• save 🔒
• work_product 🔒
  Functions for saving and removing intermediate work products.
