Add `// run-pass` to collection of tests. 2018-09-04 12:05:53 +02:00			`// run-pass`
test: Make manual changes to deal with the fallout from removal of `~[T]` in test, libgetopts, compiletest, librustdoc, and libnum. 2014-03-05 15:28:08 -08:00
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
Mass rename uint/int to usize/isize Now that support has been removed, all lingering use cases are renamed. 2015-03-25 17:06:52 -07:00			`fn want_slice(v: &[isize]) -> isize {`
allow mutable vectors and so forth to be used as immutable slices 2012-05-31 14:02:39 -07:00			`let mut sum = 0;`
`for x in xs.iter()` -> `for x in &xs` 2015-01-31 12:20:46 -05:00			`for i in v { sum += *i; }`

Changed most vec! invocations to use square braces Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets. 2016-10-29 22:54:04 +01:00			`assert_eq!(has_mut_vec(vec![1, 2, 3]), 6);`
