2016-09-19Remove data structure specialization for .zip() iteratorUlrik Sverdrup-38/+14
Go back on half the specialization, the part that changed the Zip struct's fields themselves depending on the types of the iterators. This means that the Zip iterator will always carry two usize fields, which are unused. If a whole for loop using a .zip() iterator is inlined, these are simply removed and have no effect. The same improvement for Zip of for example slice iterators remain, and they still optimize well. However, like when the specialization of zip was merged, the compiler is still very sensistive to the exact context. For example this code only autovectorizes if the function is used, not if the code in zip_sum_i32 is inserted inline it was called: ``` fn zip_sum_i32(xs: &[i32], ys: &[i32]) -> i32 { let mut s = 0; for (&x, &y) in xs.iter().zip(ys) { s += x * y; } s } fn zipdot_i32_default_zip(b: &mut test::Bencher) { let xs = vec![1; 1024]; let ys = vec![1; 1024]; b.iter(|| { zip_sum_i32(&xs, &ys) }) } ``` Include a test that checks that Zip<T, U> is covariant w.r.t. T and U.

2016-08-16Auto merge of #35162 - canndrew:bang_type_coerced, r=nikomatsakisbors-0/+59
Implement the `!` type This implements the never type (`!`) and hides it behind the feature gate `#[feature(never_type)]`. With the feature gate off, things should build as normal (although some error messages may be different). With the gate on, `!` is usable as a type and diverging type variables (ie. types that are unconstrained by anything in the code) will default to `!` instead of `()`.
2016-08-14Rollup merge of #35622 - matthew-piziak:convert-docs-typos, r=apasel422Eduard-Mihai Burtescu-4/+4
fix small typos in std::convert documentation Fix subject-verb agreement in copypasta: "`AsRef` dereference" to "`AsRef` dereferences". Formalize "eg" to "e.g." Italicization of common Latin abbreviations seems to be going out of style in written English, so I left it plain.
2016-08-14Rollup merge of #35588 - Antti:fix-atomics-docs, r=alexcrichtonEduard-Mihai Burtescu-1/+1
Use an existing constant name as an example. By reading atomics documentation I tried to use `INIT_ATOMIC_BOOL`, which I couldn't find. Turns out it was renamed to `ATOMIC_BOOL_INIT`.
2016-08-14Rollup merge of #35392 - malbarbo:cell-from, r=brsonEduard-Mihai Burtescu-0/+22
Implement From for Cell, RefCell and UnsafeCell Considering that `From` is implemented for `Box`, `Rc` and `Arc`, it seems [reasonable](https://internals.rust-lang.org/t/implementing-from-t-for-other-std-types/3744) to implement it for `Cell`, `RefCell` and `UnsafeCell`.

2016-08-13Control usage of `!` through a feature gate.Andrew Cann-0/+1
Adds the `bang_type` feature gate. `!` in a non-return-type position now relies on that feature.

Remove redundant `&mut ref mut` in doc for Result::as_mut() While a good example of how `&mut ref mut` is a no-op, I don't think we should show that here :) See https://users.rust-lang.org/t/mnemonic-for-reading-qualifiers/6853 r? @steveklabnik

2016-07-30Rollup merge of #35058 - jethrogb:no_panic_abs, r=alexcrichtonManish Goregaokar-0/+84
Add non-panicking abs() functions to all signed integer types. Currently, calling abs() on one of the signed integer types might panic (in debug mode at least) because the absolute value of the largest negative value can not be represented in that signed type. Unlike all other integer operations, there is currently not a non-panicking version on this function. This seems to just be an oversight in the design, therefore just adding it now.

2016-07-28Auto merge of #34485 - tbu-:pr_unicode_debug_str, r=alexcrichtonbors-11/+744
Escape fewer Unicode codepoints in `Debug` impl of `str` Use the same procedure as Python to determine whether a character is printable, described in [PEP 3138]. In particular, this means that the following character classes are escaped: - Cc (Other, Control) - Cf (Other, Format) - Cs (Other, Surrogate), even though they can't appear in Rust strings - Co (Other, Private Use) - Cn (Other, Not Assigned) - Zl (Separator, Line) - Zp (Separator, Paragraph) - Zs (Separator, Space), except for the ASCII space `' '` `0x20` This allows for user-friendly inspection of strings that are not English (e.g. compare `"\u{e9}\u{e8}\u{ea}"` to `"éèê"`). Fixes #34318. CC #34422. [PEP 3138]: https://www.python.org/dev/peps/pep-3138/
