From cb02a370428afaae76db59080befe88b8c97e14d Mon Sep 17 00:00:00 2001 From: Huon Wilson Date: Tue, 28 Jan 2014 00:20:50 +1100 Subject: syntax: make deriving have slightly less cryptic error messages. This unfortunately changes an error like error: mismatched types: expected `&&NotClone` but found `&NotClone` into error: type `NotClone` does not implement any method in scope named `clone` --- .../deriving-no-inner-impl-error-message.rs | 24 ++++++++++++++++++++++ .../deriving-span-TotalEq-enum-struct-variant.rs | 1 - .../compile-fail/deriving-span-TotalEq-enum.rs | 1 - .../compile-fail/deriving-span-TotalEq-struct.rs | 1 - .../deriving-span-TotalEq-tuple-struct.rs | 1 - .../deriving-span-TotalOrd-enum-struct-variant.rs | 1 - .../compile-fail/deriving-span-TotalOrd-enum.rs | 1 - .../compile-fail/deriving-span-TotalOrd-struct.rs | 1 - .../deriving-span-TotalOrd-tuple-struct.rs | 1 - .../deriving-self-lifetime-totalord-totaleq.rs | 3 +++ src/test/run-pass/deriving-self-lifetime.rs | 2 ++ src/test/run-pass/regions-mock-tcx.rs | 10 ++++++++- 12 files changed, 38 insertions(+), 9 deletions(-) create mode 100644 src/test/compile-fail/deriving-no-inner-impl-error-message.rs (limited to 'src/test') diff --git a/src/test/compile-fail/deriving-no-inner-impl-error-message.rs b/src/test/compile-fail/deriving-no-inner-impl-error-message.rs new file mode 100644 index 00000000000..604aa0dd06a --- /dev/null +++ b/src/test/compile-fail/deriving-no-inner-impl-error-message.rs @@ -0,0 +1,24 @@ +// Copyright 2014 The Rust Project Developers.
