Trait zerocopy::Unaligned

source ·
pub unsafe trait Unaligned { }
Expand description

Types with no alignment requirement.

WARNING: Do not implement this trait yourself! Instead, use #[derive(Unaligned)] (requires the derive Cargo feature).

If T: Unaligned, then align_of::<T>() == 1.

Safety

This section describes what is required in order for T: Unaligned, and what unsafe code may assume of such types. #[derive(Unaligned)] only permits types which satisfy these requirements. If you don’t plan on implementing Unaligned manually, and you don’t plan on writing unsafe code that operates on Unaligned types, then you don’t need to read this section.

If T: Unaligned, then unsafe code may assume that it is sound to produce a reference to T at any memory location regardless of alignment. If a type is marked as Unaligned which violates this contract, it may cause undefined behavior.
