Functions

func AllFieldTags

func AllFieldTags(req interface{}, key string) []string

func AllTagsValues

func AllTagsValues(req interface{}, key string) map[string]interface{}

only get export Fields

func IsZeroValue

func IsZeroValue(v reflect.Value) bool

cmd/compile/internal/gc/dump.go

func NonzeroFieldTags

func NonzeroFieldTags(req interface{}, key string) []string

req must be struct(Not pointer to struct), or return nil(tt.Field() will panic) key for tag , db or json, if key is empty, use field name instead

func ReflectValue

func ReflectValue(valueType string, value interface{}) (reflect.Value, error)

ReflectValue converts interface{} to reflect.Value based on string type

func RetrieveStructField

func RetrieveStructField(req interface{}, name string) string

func TruncateBytes

func TruncateBytes(req interface{}) interface{}

https://stackoverflow.com/questions/6395076/using-reflect-how-do-you-set-the-value-of-a-struct-field truncate []byte, [][]byte, not support others, eg: [][][]byte struct must use pointer of sturct, or not rewrite it

func TrySetStructFiled

func TrySetStructFiled(req interface{}, name, value string)

Types

type ErrUnsupportedType

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

ErrUnsupportedType ...

func NewErrUnsupportedType

func NewErrUnsupportedType(valueType string) ErrUnsupportedType

NewErrUnsupportedType returns new ErrUnsupportedType

func (ErrUnsupportedType) Error

func (e ErrUnsupportedType) Error() string

Error method so we implement the error interface
