From f6db0ef9464a17fa6e547e755b1b5dfa09af9499 Mon Sep 17 00:00:00 2001 From: Huon Wilson Date: Sun, 23 Mar 2014 22:54:42 +1100 Subject: std: remove the `equals` method from `TotalEq`. `TotalEq` is now just an assertion about the `Eq` impl of a type (i.e. `==` is a total equality if a type implements `TotalEq`) so the extra method is just confusing. Also, a new method magically appeared as a hack to allow deriving to assert that the contents of a struct/enum are also TotalEq, because the deriving infrastructure makes it very hard to do anything but create a trait method. (You didn't hear about this horrible work-around from me :(.) --- src/libstd/unit.rs | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-) (limited to 'src/libstd/unit.rs') diff --git a/src/libstd/unit.rs b/src/libstd/unit.rs index b23dafbca69..38307f415ac 100644 --- a/src/libstd/unit.rs +++ b/src/libstd/unit.rs @@ -37,10 +37,7 @@ impl TotalOrd for () { } #[cfg(not(test))] -impl TotalEq for () { - #[inline] - fn equals(&self, _other: &()) -> bool { true } -} +impl TotalEq for () {} #[cfg(not(test))] impl Default for () { -- cgit 1.4.1-3-g733a5
