Functions

func ConvertAssign

func ConvertAssign(dest interface{}, src []byte) error

ConvertAssign 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 DataScanBytes

func DataScanBytes(key []string, data [][][]byte, v interface{}, fn func(reflect.StructField) string) (int, error)

DataScanBytes fill in key and data to v

func DataScanChannel

func DataScanChannel(key []string, data chan [][]byte, v interface{},
	fn func(reflect.StructField) string, f int) (int, error)

DataScanChannel fill in key and data to v

func MakeFieldName

func MakeFieldName(tag string) func(fn reflect.StructField) string

MakeFieldName returns a function that gets the value of a field

func RowsLimitBytes

func RowsLimitBytes(rows Rows, limit int) ([]string, [][][]byte, error)

RowsLimitBytes if limit >= 0 Read maximum rows limit else < 0 Not limited

func RowsLimitChannel

func RowsLimitChannel(rows Rows, limit int) ([]string, chan [][]byte, error)

RowsLimitChannel if limit >= 0 Read maximum rows limit else < 0 Not limited

func RowsScan

func RowsScan(rows Rows, v interface{}, limit int,
	fn func(reflect.StructField) string, f int) (int, error)

RowsScan v should be a pointer type. SupportType:

Basic Type
Slices
Array
Pointer
Struct
map[string]string
*map[string]string
map[string][]byte
*map[string][]byte

Example:

[100]map[string]string   Get 100 lines to map
map[string]string        Get 1 lines to map
[]*struct                All to *struct
*[100]struct             Get 100 lines to struct
var ret [100]map[string]string
DataScan(key, data, &ret)

func RowsScanBytes

func RowsScanBytes(rows Rows, v interface{}, limit int,
	fn func(reflect.StructField) string) (int, error)

RowsScanBytes fill in rows to v

func RowsScanChannel

func RowsScanChannel(rows Rows, v interface{}, limit int,
	fn func(reflect.StructField) string, f int) (int, error)

RowsScanChannel fill in rows to v

func StringToBytes

func StringToBytes(v string) []byte

StringToBytes string to []byte

func StringsToBytess

func StringsToBytess(v []string) [][]byte

StringsToBytess []string to [][]byte

func StringssToBytesss

func StringssToBytesss(v [][]string) [][][]byte

StringssToBytesss [][]string to [][][]byte

Types

type Rows

type Rows interface {
	Next() bool
	Columns() ([]string, error)
	Scan(dest ...interface{}) error
	Err() error
	Close() error
}

Rows Handle multiline interfaces
