Expand description

Assert that two layout versions have compatible fingerprints.

Fails at compile time if the assertion doesn’t hold. Use this in tests and CI to catch accidental schema breaks.

ⓘ
// Assert V2 is a strict superset of V1 (append-only):
hopper_assert_compatible!(VaultV1, VaultV2, append);

// Assert two layouts have different fingerprints (version bump required):
hopper_assert_compatible!(VaultV1, VaultV2, differs);
