source · Expand description
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.
- 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: - 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 save/load the dep-graph from files.
- save 🔒
- Functions for saving and removing intermediate work products.
