The free-standing functions in f32, f64, i8, i16, i32, i64, u8, u16,
u32, u64, float, int, and uint are replaced with generic functions in
num instead.
This means that instead of having to know everywhere what the type is, like
~~~
f64::sin(x)
~~~
You can simply write code that uses the type-generic versions in num instead, this works for all types that implement the corresponding trait in num.
~~~
num::sin(x)
~~~
Note 1: If you were previously using any of those functions, just replace them
with the corresponding function with the same name in num.
Note 2: If you were using a function that corresponds to an operator, use the
operator instead.
Note 3: This is just https://github.com/mozilla/rust/pull/7090 reopened against master.
Correct treatment of irrefutable patterns. The old code was wrong in many, many ways. `ref` bindings didn't work, it sometimes copied when it should have moved, the borrow checker didn't even look at such patterns at all, we weren't consistent about preventing values with destructors from being pulled apart, etc.

In an ideal world, the AST would be completely sendable, this gets us a step closer.
It removes the local heap allocations for `view_item`, `Path`, `Lifetime` `trait_ref` `OptVec<TyParamBounds>` and `Ty`. There are also a few other smaller changes I made as things went along.
Also, makes the pretty-printer use & instead of @ as much as possible,
which will help with later changes, though in the interim has produced
some... interesting constructs.
Change the signature of Iterator.size_hint() to always have a lower bound.
Implement .size_hint() on all remaining iterators (if it differs from the default).
Continuation of #7430.
I haven't removed the `map` method, since the replacement `v.iter().transform(f).collect::<~[SomeType]>()` is a little ridiculous at the moment.
Mostly just low-haning fruit, i.e. function arguments that were @ even
though & would work just as well.
Reduces librustc.so size by 200k when compiling without -O, by 100k when
compiling with -O.
Move all the colors into a nested mod named color instead of prefixing
with "color_".
Define a new type color::Color, and make this a u16 instead of a u8 (to
allow for easy comparisons against num_colors, which is a u16).
Remove color_supported and replace it with num_colors.
Teach fg() and bg() to "dim" bright colors down to the normal intensity
if num_colors isn't high enough.
Remove unnecessary copies, and fix a bug where a terminfo parse failure
would try to use the wrong error and end up failing.
This sets the `get_tydesc()` return type correctly and removes the intrinsic module. See #3730, #3475.
Update: this now also removes the unused shape fields in tydescs.
This adds both `static mut` items and `static mut` foreign items. This involved changing far less code than I thought it was going to, but the tests seem to pass and the variables seem functional.
I'm more than willing to write more tests, so suggestions are welcome!
Closes#553
the `test/run-pass/class-trait-bounded-param.rs` test was xfailed and
written in an ancient dialect of Rust so I've just removed it
this also removes `to_vec` from DList because it's provided by
`std::iter::to_vec`
an Iterator implementation is added for OptVec but some transitional
internal iterator methods are still left
I removed the `static-method-test.rs` test because it was heavily based
on `BaseIter` and there are plenty of other more complex uses of static
methods anyway.
Closes#7180 and #7179.
Before, the `deriving(ToStr)` attribute was essentially `fmt!("%?")`. This changes it to recursively invoke `to_str()` on fields instead of relying on `fmt!`-style things. This seems more natural to me and what should actually be expected.
The removed test for issue #2611 is well covered by the `std::iterator`
module itself.
This adds the `count` method to `IteratorUtil` to replace `EqIter`.
This change prevents the indentation in code blocks inside the /// doc comments
from being eaten. The indentation that is the same across the consecutive doc
comments is removed by the uindent_pass in librustdoc.
This allows mass-initialization of large structs without having to specify all the fields.
I'm a bit hesitant, but I wanted to get this out there. I don't really like using the `Zero` trait, because it doesn't really make sense for a type like `HashMap` to use `Zero` as the 'blank allocation' trait. In theory there'd be a new trait, but then that's adding cruft to the language which may not necessarily need to be there.
I do think that this can be useful, but I only implemented `Zero` on the basic types where I thought it made sense, so it may not be all that usable yet. (opinions?)
Moves all the remaining functions that could reasonably be methods to be methods, except for some FFI ones (which I believe @erickt is working on, possibly) and `each_split_within`, since I'm not really sure the details of it (I believe @kimundi wrote the current implementation, so maybe he could convert it to an external iterator method on `StrSlice`, e.g. `word_wrap_iter(&self) -> WordWrapIterator<'self>`, where `WordWrapIterator` impls `Iterator<&'self str>`. It probably won't be too hard, since it's already a state machine.)
This also cleans up the comparison impls for the string types, except I'm not sure how the lang items `eq_str` and `eq_str_uniq` need to be handled, so they (`eq_slice` and `eq`) remain stand-alone functions.
r? (yes, the review request is back, now that I got it building against incom... I mean master!)
(Attempting to port from orphaned pull-request #6764 )
Fix for #3961. Also includes a test case to illustrate the issues. (All of the entries that say "should align" should align with each other, and the four lines near the end that say "compare _" for _ in {A,B,C,D} should line up with each other.)
Before applying this change set:
-- the "(should align)"'s are all over the place, and the form/line feeding spaces are not cut out as one might or might not expect.
-- compare B and D do not match A and C.
(To be honest, its hard to really say what the right behavior is here, and people who are expecting a particular behavior out of a pretty printer in these cases may well get burned.)
This fixes the strange random crashes in compile-fail tests.

Previously, this was not a global call, and so when `#[deriving(Rand)]`
was in any module other than the top-level one, it failed (unless there
was a `use std;` in scope).
Also, fix a minor inconsistency between uints and u32s for this piece
of code.
This almost removes the StringRef wrapper, since all strings are
Equiv-alent now. Removes a lot of `/* bad */ copy *`'s, and converts
several things to be &'static str (the lint table and the intrinsics
table).
There are many instances of .to_managed(), unfortunately.
This removes some unnecessary allocations in the lexer, the typechecker and the metadata decoder. Reduces the time spent in the parsing and typechecking passes by about 10% for me.
As the comment said, the subtraction is bogus for multibyte characters.
Fortunately, we can just use last_pos instead of pos to get the correct
position without any subtraction hackery.
