get_with_default (nee from_maybe) => get_default
with_option (nee maybe) => map_default
with_option_do (nee may) => iter
As per discussion of 21be1379d561b6679a8a2ea47dce88f948c5acca
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.
(This hack will go away soon.)
Issue #1619
- we now distinguish bound/free parameters (see region-param
test case for why this is necessary)
- we also track bounds on region variables
- also, restructure fold_ty() to have multiple variants without
duplication instead of one overloaded folder. This also allows
for using block functions.
Allow class methods to have type parameters (this is a change from the
original classes proposal).
Add test cases for classes with type parameters, and classes with methods
that have their own type parameters.
from_maybe => get_with_default
maybe => with_option
may => with_option_do
I know these names are kind of ridiculous, but it's the best I could think of.
Feel free to bikeshed. Closes#2081
Allow writing self.f() within a class that has a method f. In a future
commit, this syntax will be required. For now, you can write either
self.f() or f().
I added a "privacy" field to all methods (whether class methods or not),
which allowed me to refactor the AST somewhat (getting rid of the
class_item type; now there's just class_member).
1. Enforce mutability declarations on class fields. Don't allow any
mutation of class fields not declared as mutable (except inside the
constructor).
2. Handle classes correctly in shape (treat classes like records).
Cross-crate method calls don't work yet. Added
run-pass/class-method-cross-crate to test that, but it's xfailed
References to fields within methods don't work yet. Added
run-pass/class-methods to test that, but it's also xfailed
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.)
