+An unknown field was specified into an enum's structure variant.
+
+Erroneous code example:
+
+```compile_fail,E0559
+enum Field {
+    Fool { x: u32 },
+}
+
+let s = Field::Fool { joke: 0 };
+// error: struct variant `Field::Fool` has no field named `joke`
+```
+
+Verify you didn't misspell the field's name or that the field exists. Example:
+
+```
+enum Field {
+    Fool { joke: u32 },
+}
+
+let s = Field::Fool { joke: 0 }; // ok!
+```
