+#### Note: this error code is no longer emitted by the compiler
+
+You implemented a trait, overriding one or more of its associated types but did
+not reimplement its default methods.
+
+Example of erroneous code:
+
+```
+#![feature(associated_type_defaults)]
+
+pub trait Foo {
+    type Assoc = u8;
+    fn bar(&self) {}
+}
+
+impl Foo for i32 {
+    // error - the following trait items need to be reimplemented as
+    //         `Assoc` was overridden: `bar`
+    type Assoc = i32;
+}
+```
+
+To fix this, add an implementation for each default method from the trait:
+
+```
+#![feature(associated_type_defaults)]
+
+pub trait Foo {
+    type Assoc = u8;
+    fn bar(&self) {}
+}
+
+impl Foo for i32 {
+    type Assoc = i32;
+    fn bar(&self) {} // ok!
+}
+```
