So the nomicon is out of date? It says Struct fields are aligned to to the 32/64bit boundary based on system architecture. Then you have #[repr(u8/u16/u32/u64)

It says Struct fields are aligned to to the 32/64bit boundary based on system architecture. Then you have #[repr(u8/u16/u32/u64)] which will align to 8/16/32/64 boundary.
- Gankro 10y agoNo you're just making stuff up. https://doc.rust-lang.org/nomicon/repr-rust.html https://doc.rust-lang.org/nomicon/repr-rust.html The bulk of this section is describing how Rust has reserved the right to reorder and pack stuff. The first example happens to be 32-bit aligned because it contains a value that is.
