Variables

var ErrNilPtr = errors.New("destination pointer is nil") // embedded in descriptive error

ErrNilPtr represents an error

Functions

func AsBigFloat

func AsBigFloat(src interface{}) (*big.Float, error)

AsBigFloat converts interface as big.Float

func AsBool

func AsBool(src interface{}) (bool, error)

AsBool convert interface as bool

func AsBytes

func AsBytes(src interface{}) ([]byte, bool)

AsBytes converts interface as bytes

func AsFloat64

func AsFloat64(src interface{}) (float64, error)

AsFloat64 convets interface as float64

func AsInt64

func AsInt64(src interface{}) (int64, error)

AsInt64 converts interface as int64

func AsString

func AsString(src interface{}) string

AsString converts interface as string

func AsTime

func AsTime(src interface{}, dbLoc *time.Location, uiLoc *time.Location) (*time.Time, error)

AsTime converts interface as time

func AsUint64

func AsUint64(src interface{}) (uint64, error)

AsUint64 converts interface as uint64

func Assign

func Assign(dest, src interface{}, originalLocation *time.Location, convertedLocation *time.Location) error

Assign copies to dest the value in src, converting it if possible. An error is returned if the copy would result in loss of information. dest should be a pointer type.

func AssignValue

func AssignValue(dv reflect.Value, src interface{}) error

AssignValue assign src as dv

func Interface2Interface

func Interface2Interface(userLocation *time.Location, v interface{}) (interface{}, error)

Interface2Interface converts interface of pointer as interface of value

func String2Time

func String2Time(s string, originalLocation *time.Location, convertedLocation *time.Location) (*time.Time, error)

String2Time converts a string to time with original location be aware for time strings (HH:mm:ss) returns zero year (LMT) for converted location

Types

type Conversion

type Conversion interface {
	ConversionFrom
	ConversionTo
}

Conversion is an interface. A type implements Conversion will according the custom method to fill into database and retrieve from database.

type ConversionFrom

type ConversionFrom interface {
	FromDB([]byte) error
}

ConversionFrom is an inteface to allow retrieve data from database

type ConversionTo

type ConversionTo interface {
	ToDB() ([]byte, error)
}

ConversionTo is an interface to allow store data to database

type EmptyScanner

type EmptyScanner struct{}

EmptyScanner represents an empty scanner which will ignore the scan

func (EmptyScanner) Scan

func (EmptyScanner) Scan(value interface{}) error

Scan implements sql.Scanner

type NullUint32

type NullUint32 struct {
	Uint32 uint32
	Valid  bool // Valid is true if Uint32 is not NULL
}

NullUint32 represents an uint32 that may be null. NullUint32 implements the Scanner interface so it can be used as a scan destination, similar to NullString.

func (*NullUint32) Scan

func (n *NullUint32) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullUint32) Value

func (n NullUint32) Value() (driver.Value, error)

Value implements the driver Valuer interface.

type NullUint64

type NullUint64 struct {
	Uint64 uint64
	Valid  bool
}

NullUint64 represents an uint64 that may be null. NullUint64 implements the Scanner interface so it can be used as a scan destination, similar to NullString.

func (*NullUint64) Scan

func (n *NullUint64) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullUint64) Value

func (n NullUint64) Value() (driver.Value, error)

Value implements the driver Valuer interface.
