7 | The argument to the `asm` macro is not well-formed. | |

70 | A clobber was surrounded by braces in the `asm` macro. | |

88 | The `Default` trait was derived on an enum. | |
89 | ||
90 | Erroneous code example: | |
91 | ||
92 | ```compile_fail,E0665 | |
93 | #[derive(Default)] | |
94 | enum Food { | |
95 | Sweet, | |
96 | Salty, | |
97 | } | |
98 | ``` | |
99 | ||
100 | The `Default` cannot be derived on an enum for the simple reason that the | |
101 | compiler doesn't know which value to pick by default whereas it can for a | |
102 | struct as long as all its fields implement the `Default` trait as well. | |
103 | ||
104 | If you still want to implement `Default` on your enum, you'll have to do it "by | |
105 | hand": | |
106 | ||
107 | ``` | |
108 | enum Food { | |
109 | Sweet, | |
110 | Salty, | |
111 | } | |
112 | ||
113 | impl Default for Food { | |
114 | fn default() -> Food { | |
115 | Food::Sweet | |
116 | } | |
117 | } | |
118 | ``` | |
