In particular, use the ast::method type to represent a class method,
and try to reuse as much iface code as possible. (This makes sense now
since I'll be allowing polymorphic class methods.)
Cross-crate metadata for classes works well enough that programs with
classes in other crates compile successfully, but output wrong results.
Checking in work so far to avoid merge hassles. (Tests are xfailed.)
This will make it easier to convert crate_ctxt into a region pointer, since
there are functions that return crate contexts. There would be no way to type
these functions if crate_ctxt had to be an inferred region pointer.
- Move io, run and rand to core.
- Remove incorrect ctypes module (use libc).
- Remove os-specific modules for os and fs.
- Split fs between core::path and core::os.
This makes it possible to move them between crates without confusion,
and to instantiate them at a point where the monomorphizing
substitutions are known.
Issue #1944
This required changing almost all users of hashmaps to import the hashmap interface first.
The `size` member in the hashmap structure was renamed to `count` to work around a name conflict.
This required changing almost all users of hashmaps to import the hashmap interface first.
The `size` member in the hashmap structure was renamed to `count` to work around a name conflict.
Programs using classes with fields only (no methods) compile and run,
as long as nothing refers to a class in a different crate (todo).
Also changed the AST representation of classes to have a separate
record for constructor info (instead of inlining the fields in the
item_class node), and fixed up spans and pretty-printing for
classes.
