pub struct AbiAndPrefAlign {
pub abi: Align,
pub pref: Align,
}
Expand description
A pair of alignments, ABI-mandated and preferred.
The “preferred” alignment is an LLVM concept that is virtually meaningless to Rust code: it is not exposed semantically to programmers nor can they meaningfully affect it. The only concern for us is that preferred alignment must not be less than the mandated alignment and thus in practice the two values are almost always identical.
An example of a rare thing actually affected by preferred alignment is aligning of statics. It is of effectively no consequence for layout in structs and on the stack.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
