+The name for an item declaration conflicts with an external crate's name.
+
+Erroneous code example:
+
+```compile_fail,E0260
+extern crate core;
+
+struct core;
+
+fn main() {}
+```
+
+There are two possible solutions:
+
+Solution #1: Rename the item.
+
+```
+extern crate core;
+
+struct xyz;
+```
+
+Solution #2: Import the crate with a different name.
+
+```
+extern crate core as xyz;
+
+struct abc;
+```
+
+See the [Declaration Statements][declaration-statements] section of the
+reference for more information about what constitutes an item declaration
+and what does not.
