+A struct's or struct-like enum variant's field was not provided.
+
+Erroneous code example:
+
+```compile_fail,E0063
+struct Foo {
+    x: i32,
+    y: i32,
+}
+
+fn main() {
+    let x = Foo { x: 0 }; // error: missing field: `y`
+}
+```
+
+Each field should be specified exactly once. Example:
+
+```
+struct Foo {
+    x: i32,
+    y: i32,
+}
+
+fn main() {
+    let x = Foo { x: 0, y: 0 }; // ok!
+}
+```
