+An associated const was implemented when another trait item was expected.
+
+Erroneous code example:
+
+```compile_fail,E0323
+trait Foo {
+    type N;
+}
+
+struct Bar;
+
+impl Foo for Bar {
+    const N : u32 = 0;
+    // error: item `N` is an associated const, which doesn't match its
+    //        trait `<Bar as Foo>`
+}
+```
+
+Please verify that the associated const wasn't misspelled and the correct trait
+was implemented. Example:
+
+```
+struct Bar;
+
+trait Foo {
+    type N;
+}
+
+impl Foo for Bar {
+    type N = u32; // ok!
+}
+```
+
+Or:
+
+```
+struct Bar;
+
+trait Foo {
+    const N : u32;
+}
+
+impl Foo for Bar {
+    const N : u32 = 0; // ok!
+}
+```
