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 14:18:55 +02:00			`//@ run-pass`
rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 13:13:15 -07:00
std: Implement stdio for `std::io` This is an implementation of RFC 899 and adds stdio functionality to the new `std::io` module. Details of the API can be found on the RFC, but from a high level: * `io::{stdin, stdout, stderr}` constructors are now available. There are also `_raw` variants for unbuffered and unlocked access. All handles are globally shared (excluding raw variants). * The stderr handle is no longer buffered. * All handles can be explicitly locked (excluding the raw variants). The `print!` and `println!` machinery has not yet been hooked up to these streams just yet. The `std::fmt::output` module has also not yet been implemented as part of this commit. 2015-02-24 23:27:20 -08:00			`use std::io::{self, Write};`
Pass the unadjusted type into the unsize_info function, which seems to be what it expects. Fixes #17322. 2014-11-07 15:18:08 -05:00

Remove even more box syntax uses from src/test Prior work, notably 6550021124451628b1efc60c59284465b109e3aa from #88316 has removed box syntax from most of the testsuite. However, some tests were left out. This commit removes box_syntax uses from more locations in src/test. Some tests that are very box syntax specific are not being migrated. 2022-07-07 04:36:10 +02:00			`let mut wr = Box::new(io::stdout()) as Box<dyn Write>;`
