Now that core exports "option" as a synonym for option::t, search-and-
replace option::t with option.
The only place that still refers to option::t are the modules in libcore
that use option, because fixing this requires a new snapshot
(forthcoming).
Since item_consts can't refer to or modify local variables, they
don't participate in typestate and thus get empty pre and
postconditions by default.
Closes#1660
This allows us to express option::map with noncopyable type
parameters, which makes sense, since the type params aren't being
copied (none doesn't contain any).
All the files below had at least one instance of the ternary operator
present in the source. All have been changed to the equivalent
if/then/else expression.
This simplifies the typechecker a bit (no more ty_param_substs_opt_and_ty)
and is needed for another experiment I'm playing with. I hope it also
makes compilation faster (the bots will tell).
Almost all of the vec functions that predicates don't have a
corresponding function that takes a single element, so this
commit renames the common fn usecase to be the default.
Removes a bunch of (eventually) unused arguments. Makes span passing to debuginfo
explicit, instead of relying on the (usually incorrect) spans held in the contexts.
Closes#1439
The methods used to implement operators now simply use
the name of the operator itself, except for unary -, which is called
min to not clash with binary -. Index is called [].
Closes#1520
When no built-in interpretation is found for one of the operators
mentioned below, the typechecker will try to turn it into a method
call with the name written next to it. For binary operators, the
method will be called on the LHS with the RHS as only parameter.
Binary:
+ op_add
- op_sub
* op_mul
/ op_div
% op_rem
& op_and
| op_or
^ op_xor
<< op_shift_left
>> op_shift_right
>>> op_ashift_right
Unary:
- op_neg
! op_not
Overloading of the indexing ([]) operator isn't finished yet.
Issue #1520
Specifically box the string (to avoid unnecessary copies) and store it
in codemap::filemap.
Remove the hack in driver::diagnostic that rereads the source from the
file and instead just get the source from the filemap.
(This commit is also a prerequisite for issue #1612)
