pub fn require_mint_freeze_authority(
mint_account: &AccountView,
expected_freeze: &Address,
) -> ProgramResultExpand description
Verify an SPL Mint account’s freeze_authority COption field
matches expected_freeze.
Same shape as require_mint_authority but reads the second
COption (bytes 46..50 for tag, 50..82 for pubkey). Exposed so the
macro surface can support a future mint::freeze_authority = X
constraint without another runtime change.
