Struct InvalidAlign 

pub struct InvalidAlign(pub usize);

The error SizeClasses::try_class_for returns when align is not a power of two (the core::alloc::Layout contract SizeClasses::class_for assumes but – on its own hot path – only debug_assert!s). Carries the offending value for diagnostics.

A plain tuple struct, not #[non_exhaustive]: match the offending value directly as Err(InvalidAlign(n)).
