"##,
+E0534: r##"
+The inline attribute was badly used.
+
+Erroneous code example:
+
+```compile_fail,E0534
+#[inline()] // error: expected one argument
+pub fn something() {}
+
+fn main() {}
+```
+
+The inline attribute can be used without arguments:
+
+```
+#[inline] // ok!
+pub fn something() {}
+
+fn main() {}
+```
+
+Or with arguments (and parens have to be used for this case!):
+
+```
+#[inline(always)] // ok!
+pub fn something() {}
+
+fn main() {}
+```
+
