+A function is using `continue` keyword incorrectly.
+
+Erroneous code example:
+
+```compile_fail,E0696
+fn continue_simple() {
+    'b: {
+        continue; // error!
+    }
+}
+fn continue_labeled() {
+    'b: {
+        continue 'b; // error!
+    }
+}
+fn continue_crossing() {
+    loop {
+        'b: {
+            continue; // error!
+        }
+    }
+}
+```
+
+Here we have used the `continue` keyword incorrectly. As we
+have seen above that `continue` pointing to a labeled block.
+
+To fix this we have to use the labeled block properly.
+For example:
+
+```
+fn continue_simple() {
+    'b: loop {
+        continue ; // ok!
+    }
+}
+fn continue_labeled() {
+    'b: loop {
+        continue 'b; // ok!
+    }
+}
+fn continue_crossing() {
+    loop {
+        'b: loop {
+            continue; // ok!
+        }
+    }
+}
+```
