+/// Assert at compile time that an expression is true.  This is similar

+///
+/// # Examples
+///
+/// ```
+/// # use qemu_api::static_assert;
+/// static_assert!("abc".len() == 3);
+/// ```
+///
+/// ```compile_fail
+/// # use qemu_api::static_assert;
+/// static_assert!("abc".len() == 2); // does not compile
