+A struct's or struct-like enum variant's field was specified more than once.
+
+Erroneous code example:
+
+```compile_fail,E0062
+struct Foo {
+    x: i32,
+}
+
+fn main() {
+    let x = Foo {
+                x: 0,
+                x: 0, // error: field `x` specified more than once
+            };
+}
+```
+
+This error indicates that during an attempt to build a struct or struct-like
+enum variant, one of the fields was specified more than once. Each field should
+be specified exactly one time. Example:
+
+```
+struct Foo {
+    x: i32,
+}
+
+fn main() {
+    let x = Foo { x: 0 }; // ok!
+}
+```
