Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 07:18:55 -05:00			`// run-pass`

std: Rename Show/String to Debug/Display This commit is an implementation of [RFC 565][rfc] which is a stabilization of the `std::fmt` module and the implementations of various formatting traits. Specifically, the following changes were performed: [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0565-show-string-guidelines.md * The `Show` trait is now deprecated, it was renamed to `Debug` * The `String` trait is now deprecated, it was renamed to `Display` * Many `Debug` and `Display` implementations were audited in accordance with the RFC and audited implementations now have the `#[stable]` attribute * Integers and floats no longer print a suffix * Smart pointers no longer print details that they are a smart pointer * Paths with `Debug` are now quoted and escape characters * The `unwrap` methods on `Result` now require `Display` instead of `Debug` * The `Error` trait no longer has a `detail` method and now requires that `Display` must be implemented. With the loss of `String`, this has moved into libcore. * `impl<E: Error> FromError<E> for Box<Error>` now exists * `derive(Show)` has been renamed to `derive(Debug)`. This is not currently warned about due to warnings being emitted on stage1+ While backwards compatibility is attempted to be maintained with a blanket implementation of `Display` for the old `String` trait (and the same for `Show`/`Debug`) this is still a breaking change due to primitives no longer implementing `String` as well as modifications such as `unwrap` and the `Error` trait. Most code is fairly straightforward to update with a rename or tweaks of method calls. [breaking-change] Closes #21436 2015-01-20 17:45:07 -06:00			`#[derive(Debug)]`

Switched to Box::new in many places. Many of the modifications putting in `Box::new` calls also include a pointer to Issue 22405, which tracks going back to `box <expr>` if possible in the future. (Still tried to use `Box<_>` where it sufficed; thus some tests still have `box_syntax` enabled, as they use a mix of `box` and `Box::new`.) Precursor for overloaded-`box` and placement-`in`; see Issue 22181. 2015-02-15 02:52:21 -06:00			`println!("{:?}", Foo(Box::new([0, 1, 2])));`
