Expand description
This is the context state available during incr. comp. hashing. It contains
enough information to transform DefId
s and HirId
s into stable DefPath
s (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.
