Types

type Decimal

type Decimal struct {
	decimal.Decimal
}

func (*Decimal) Scan

func (d *Decimal) Scan(val interface{}) error

Scan implements sql.Scanner.

func (*Decimal) Value

func (d *Decimal) Value() (driver.Value, error)

Value implements driver.Valuer.

type LengthError

type LengthError struct {
	Part string // "integral" or "fractional"
	N    int    // length of invalid part
	// contains filtered or unexported fields
}

LengthError is returned from Decimal.Value when either its integral (digits before the decimal point) or fractional (digits after the decimal point) parts are too long for PostgresSQL.

func (LengthError) Error

func (e LengthError) Error() string

type NullDecimal

type NullDecimal struct {
	Decimal
	Valid bool
}

func (*NullDecimal) Scan

func (n *NullDecimal) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullDecimal) Value

func (n NullDecimal) Value() (driver.Value, error)

Value implements the driver Valuer interface.
