Error code E0693

align representation hint was incorrectly declared.

Erroneous code examples:

#![allow(unused)] fn main() { #[repr(align=8)] // error! struct Align8(i8); #[repr(align="8")] // error! struct Align8(i8); }

This is a syntax error at the level of attribute declarations. The proper syntax for align representation hint is the following:

#![allow(unused)] fn main() { #[repr(align(8))] // ok! struct Align8(i8); }
