This update contains a collection of improvements to metadata handling, parsing, and indexing. Chiefly, the metadata reader now treats types, functions, and constants all as first-class citizens. Previously, only types were indexed which made sense for traditional WinRT metadata but Win32 metadata introduced free functions and constants that were harder to search for. No more!
This allows riddle to streamline how it handles filtering for APIs across namespace- or standalone-style code generation.
There's a bunch of code movement in the
windows
andwindows-sys
crates as a result of this indexing where constants are now sorted properly according to kind, but otherwise appear in the same modules and are unchanged.
