Expand description

This is the context state available during incr. comp. hashing. It contains enough information to transform DefIds and HirIds into stable DefPaths (i.e., a reference to the TyCtxt) and it holds a few caches for speeding up various things (e.g., each DefId/DefPath is only hashed once).

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
