 "##,
 
+E0535: r##"
+An unknown argument was given to inline attribute.
+
+Erroneous code example:
+
+```compile_fail,E0535
+#[inline(unknown)] // error: invalid argument
+pub fn something() {}
+
+fn main() {}
+```
+
+The inline attribute only knows two arguments:
+
+ * always
+ * never
+
+All other arguments given to the inline attribute will return this error.
+Example:
+
+```
+#[inline(never)] // ok!
+pub fn something() {}
+
+fn main() {}
+```
