+Pattern arm did not match expected kind.
+
+Erroneous code example:
+
+```compile_fail,E0532
+enum State {
+    Succeeded,
+    Failed(String),
+}
+
+fn print_on_failure(state: &State) {
+    match *state {
+        // error: expected unit struct, unit variant or constant, found tuple
+        //        variant `State::Failed`
+        State::Failed => println!("Failed"),
+        _ => ()
+    }
+}
+```
+
+To fix this error, ensure the match arm kind is the same as the expression
+matched.
+
+Fixed example:
+
+```
+enum State {
+    Succeeded,
+    Failed(String),
+}
+
+fn print_on_failure(state: &State) {
+    match *state {
+        State::Failed(ref msg) => println!("Failed with {}", msg),
+        _ => ()
+    }
+}
+```
