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 save/load the dep-graph from files.

save 🔒

work_product 🔒

Functions for saving and removing intermediate work products.
