Public Member Functions inherited from FeeFrac
constexpr	FeeFrac () noexcept
	Construct an IsEmpty() FeeFrac.
constexpr	FeeFrac (int64_t f, int32_t s) noexcept
	Construct a FeeFrac with specified fee and size.
constexpr	FeeFrac (const FeeFrac &) noexcept=default
constexpr FeeFrac &	operator= (const FeeFrac &) noexcept=default
bool	IsEmpty () const noexcept
	Check if this is empty (size and fee are 0).
void	operator+= (const FeeFrac &other) noexcept
	Add fee and size of another FeeFrac to this one.
void	operator-= (const FeeFrac &other) noexcept
	Subtract fee and size of another FeeFrac from this one.
template<bool RoundDown>
int64_t	EvaluateFee (int32_t at_size) const noexcept
	Compute the fee for a given size at_size using this object's feerate.
int64_t	EvaluateFeeDown (int32_t at_size) const noexcept
	Compute the fee for a given size at_size using this object's feerate, rounding down.
int64_t	EvaluateFeeUp (int32_t at_size) const noexcept
	Compute the fee for a given size at_size using this object's feerate, rounding up.

Static Public Member Functions
static FeePerUnit	FromFeeFrac (const FeeFrac &feefrac) noexcept
	Convert a FeeFrac to a FeePerUnit.
Static Public Member Functions inherited from FeeFrac
static std::pair< int64_t, uint32_t >	MulFallback (int64_t a, int32_t b) noexcept
	Helper function for 32*64 signed multiplication, returning an unspecified but totally ordered type.
static int64_t	DivFallback (std::pair< int64_t, uint32_t > n, int32_t d, bool round_down) noexcept
	Helper function for 96/32 signed division, rounding towards negative infinity (if round_down) or positive infinity (if !round_down).
