type Float ¶

type Float interface {
	~float32 | ~float64
}

Float is a type constraint that matches any floating-point type.

type Integer ¶

type Integer interface {
	Signed | Unsigned
}

Integer is a constraint that permits any integer type. If future releases of Go add new predeclared integer types, this constraint will be modified to include them.

type Money ¶

type Money int64

Money value type: first 9 numbers it's float part Example:

1_000000000 => 1    $
0_010000000 => 0.01 $

func MoneyFloat[T Float](amount T) Money

func MoneyInt[T Integer](amount T) Money

func (m *Money) DecodeValue(v any) (err error)

func (m Money) F64() float64

func (m Money) Float64() float64

func (m Money) I64() int64

func (m Money) Int64() int64

func (m Money) MarshalJSON() ([]byte, error)

func (m *Money) Scan(value any) error

func (m *Money) SetFromFloat64(v float64)

func (m *Money) SetFromInt64(v int64)

func (m Money) String() string

func (m *Money) UnmarshalJSON(b []byte) error

func (m *Money) UnmarshalYAML(unmarshal func(any) error) error

func (m Money) Value() (driver.Value, error)

type Signed ¶

type Signed interface {
	~int | ~int8 | ~int16 | ~int32 | ~int64
}

Signed is a constraint that permits any signed integer type. If future releases of Go add new predeclared signed integer types, this constraint will be modified to include them.

type Unsigned ¶

type Unsigned interface {
	~uint | ~uint8 | ~uint16 | ~uint32 | ~uint64 | ~uintptr
}

Unsigned is a constraint that permits any unsigned integer type. If future releases of Go add new predeclared unsigned integer types, this constraint will be modified to include them.
