[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 23:51:35 +02:00			`#![allow(unused_assignments)]`
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
check-fast fallout from removing export, r=burningtree 2013-02-01 19:43:17 -08:00			`pub fn main() {`
Remove box syntax from most places in src/test outside of the issues dir 2021-08-25 02:39:40 +02:00			`let i: Box<_> = Box::new(1);`

Drop the previous value when copying one unique box local to another Issue #409 2011-09-22 13:51:40 -07:00			`// Should drop the previous value of j`

Use assert_eq! rather than assert! where possible 2013-05-18 22:02:45 -04:00			`assert_eq!(*j, 1);`
