[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ 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
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 select<'r>(x: &'r Option<isize>, y: &'r Option<isize>) -> &'r Option<isize> {`

Updated std::Option, std::Either and std::Result - Made naming schemes consistent between Option, Result and Either - Changed Options Add implementation to work like the maybe monad (return None if any of the inputs is None) - Removed duplicate Option::get and renamed all related functions to use the term `unwrap` instead 2013-08-04 01:59:24 +02:00			`assert_eq!(select(&x, &y).unwrap(), 3);`
