[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
fallout: run-pass tests that use box. (many could be ported to `Box::new` instead in the future.) 2015-01-08 02:25:56 +01:00
Move replace and swap to std::mem. Get rid of std::util Also move Void to std::any, move drop to std::mem and reexport in prelude. 2014-02-01 04:35:36 +08:00			`use std::mem::swap;`
Stop using the '<->' operator 2013-05-06 00:42:54 -04:00
