pub fn load_lib_cache(sub_root: &Path) -> Option<CachedBuild>Expand description
Load a sub-project’s cache as a CachedBuild.
This is a simplified version of load_reference_cache_with_report that
does not validate config fingerprints or file hashes — we just load
whatever shards are on disk. Sub-caches are used read-only for cross-file
reference lookup; staleness is acceptable.
