Struct Layout 

pub struct Layout(/* private fields */);

An opaque buffer-layout token. See Target for why this is a newtype, why the ordinals are wire, and why Debug is hand-written.

Ord is load-bearing beyond hashing here: select_layout resolves a port’s admissible layouts with .min(), so the ordinal order IS the selection rule, and two further sites sort or compare layouts to break routing ties. Derived Ord over the u32 preserves all three exactly.
