+A struct pattern attempted to extract a non-existent field from a struct.

-// Correct matching.
-struct Thing {
-    x: u32,
-    y: u32
-}
-
-let thing = Thing { x: 1, y: 2 };
-
-match thing {
-    Thing { x: xfield, y: yfield } => {}
-}

-If you are using shorthand field patterns but want to refer to the struct field
-by a different name, you should rename it explicitly.

-Change this:
+Erroneous code example:
 
 ```compile_fail,E0026
 struct Thing {
     x: u32,
-    y: u32
+    y: u32,
 }
 
 let thing = Thing { x: 0, y: 0 };
 
 match thing {
-    Thing { x, z } => {}
+    Thing { x, z } => {} // error: `Thing::z` field doesn't exist
 }
 ```
