+This error occurs when you defined methods or associated functions with same
+name.
+
+Erroneous code example:
+
+```compile_fail,E0592
+struct Foo;
+
+impl Foo {
+    fn bar() {} // previous definition here
+}
+
+impl Foo {
+    fn bar() {} // duplicate definition here
+}
+```
+
+A similar error is E0201. The difference is whether there is one declaration
+block or not. To avoid this error, you must give each `fn` a unique name.
+
+```
+struct Foo;
+
+impl Foo {
+    fn bar() {}
+}
+
+impl Foo {
+    fn baz() {} // define with different name
+}
+```
