Types

type BigInt

type BigInt struct {
	*big.Int
}

BigInt is a large integer data type that corresponds to a NUMERIC in a database.

func NewBigInt

func NewBigInt(bi *big.Int) *BigInt

func NewBigIntZero

func NewBigIntZero() *BigInt

func (*BigInt) Cmp

func (bi *BigInt) Cmp(a *BigInt) int

func (*BigInt) IsZero

func (bi *BigInt) IsZero() bool

func (BigInt) MarshalJSON

func (bi BigInt) MarshalJSON() ([]byte, error)

func (*BigInt) Scan

func (bi *BigInt) Scan(value interface{}) error

func (*BigInt) SetUint64

func (bi *BigInt) SetUint64(val uint64) *BigInt

func (*BigInt) UnmarshalJSON

func (bi *BigInt) UnmarshalJSON(data []byte) error

func (*BigInt) Value

func (bi *BigInt) Value() (driver.Value, error)

bi should not be a pointer but it seems like we are pleasing the Valuer interface. This needs some additional testing.

type ByteArray

type ByteArray []byte

ByteArray is a type that corresponds to BYTEA in a database. It supports marshalling and unmarshalling from JSON, as well as implementing the sql.Scanner interface with NULL handling.

func (ByteArray) MarshalJSON

func (ba ByteArray) MarshalJSON() ([]byte, error)

func (*ByteArray) Scan

func (ba *ByteArray) Scan(value interface{}) error

func (ByteArray) String

func (ba ByteArray) String() string

func (*ByteArray) UnmarshalJSON

func (ba *ByteArray) UnmarshalJSON(data []byte) error

func (ByteArray) Value

func (ba ByteArray) Value() (driver.Value, error)

type Database

type Database interface {
	Close() error // Close database

	// SQL
	RegisterNotification(context.Context, NotificationName, NotificationCallback, any) error
	UnregisterNotification(NotificationName) error
}

type DuplicateError

type DuplicateError string

func (DuplicateError) Error

func (de DuplicateError) Error() string

func (DuplicateError) Is

func (de DuplicateError) Is(target error) bool

type NotificationCallback

type NotificationCallback func(string, string, interface{}, interface{})

NotificationCallback is a callback function for a database notification.

type NotificationName

type NotificationName string

NotificationName identifies a database notification type.

type TimeZone

type TimeZone struct {
	// contains filtered or unexported fields
}

TimeZone is a type that encodes to and decodes from a +/-hh:mm string.

type Timestamp

type Timestamp struct {
	time.Time
}

Timestamp is a type that corresponds to a TIMESTAMP in a database. It supports marshalling and unmarshalling from JSON, as well as implementing the sql.Scanner interface with NULL handling.
