[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ 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
librustc: Implement lifetime elision. This implements RFC 39. Omitted lifetimes in return values will now be inferred to more useful defaults, and an error is reported if a lifetime in a return type is omitted and one of the two lifetime elision rules does not specify what it should be. This primarily breaks two uncommon code patterns. The first is this: unsafe fn get_foo_out_of_thin_air() -> &Foo { ... } This should be changed to: unsafe fn get_foo_out_of_thin_air() -> &'static Foo { ... } The second pattern that needs to be changed is this: enum MaybeBorrowed<'a> { Borrowed(&'a str), Owned(String), } fn foo() -> MaybeBorrowed { Owned(format!("hello world")) } Change code like this to: enum MaybeBorrowed<'a> { Borrowed(&'a str), Owned(String), } fn foo() -> MaybeBorrowed<'static> { Owned(format!("hello world")) } Closes #15552.

check-fast fallout from removing export, r=burningtree 2013-02-01 19:43:17 -08:00			`pub fn main() {`
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			`let v = vec![1, 2, 3];`
cleanup: replace `as[_mut]_slice()` calls with deref coercions 2015-02-01 21:53:25 -05:00			`let x = view(&v);`
			`let y = view(x);`
Remove a large amount of deprecated functionality Spring cleaning is here! In the Fall! This commit removes quite a large amount of deprecated functionality from the standard libraries. I tried to ensure that only old deprecated functionality was removed. This is removing lots and lots of deprecated features, so this is a breaking change. Please consult the deprecation messages of the deleted code to see how to migrate code forward if it still needs migration.
