func Bool ¶

func Bool(i interface{}) bool

Bool converts <i> to bool. It returns false if <i> is: false, "", 0, "false", "off", empty slice/map.

func Byte ¶

func Byte(i interface{}) byte

Byte converts <i> to byte.

func Bytes ¶

func Bytes(i interface{}) []byte

Bytes converts <i> to []byte.

func Convert ¶

func Convert(i interface{}, t string, params ...interface{}) interface{}

Convert converts the variable <i> to the type <t>, the type <t> is specified by string. The unnecessary parameter <params> is used for additional parameter passing.

func Duration ¶

func Duration(i interface{}) time.Duration

Duration converts <i> to time.Duration. If <i> is string, then it uses time.ParseDuration to convert it. If <i> is numeric, then it converts <i> as nanoseconds.

func Float32 ¶

func Float32(i interface{}) float32

Float32 converts <i> to float32.

func Float64 ¶

func Float64(i interface{}) float64

Float64 converts <i> to float64.

func Floats ¶

func Floats(i interface{}) []float64

Strings converts <i> to []float64.

func GTime ¶

func GTime(i interface{}, format ...string) *gtime.Time

GTime converts <i> to *gtime.Time. The parameter <format> can be used to specify the format of <i>. If no <format> given, it converts <i> using gtime.NewFromTimeStamp if <i> is numeric, or using gtime.StrToTime if <i> is string.

func Int ¶

func Int(i interface{}) int

Int converts <i> to int.

func Int16 ¶

func Int16(i interface{}) int16

Int16 converts <i> to int16.

func Int32 ¶

func Int32(i interface{}) int32

Int32 converts <i> to int32.

func Int64 ¶

func Int64(i interface{}) int64

Int64 converts <i> to int64.

func Int8 ¶

func Int8(i interface{}) int8

Int8 converts <i> to int8.

func Interfaces ¶

func Interfaces(i interface{}) []interface{}

Interfaces converts <i> to []interface{}.

func Ints ¶

func Ints(i interface{}) []int

Ints converts <i> to []int.

func Map ¶

func Map(value interface{}, tags ...string) map[string]interface{}

Map converts any variable <value> to map[string]interface{}.

If the parameter <value> is not a map/struct/*struct type, then the conversion will fail and returns nil.

If <value> is a struct/*struct object, the second parameter <tags> specifies the most priority tags that will be detected, otherwise it detects the tags in order of: gconv, json, and then the field name.

func MapDeep ¶

func MapDeep(value interface{}, tags ...string) map[string]interface{}

MapDeep do Map function recursively. See Map.

func Maps ¶

func Maps(value interface{}, tags ...string) []map[string]interface{}

Maps converts <i> to []map[string]interface{}.

func MapsDeep ¶

func MapsDeep(value interface{}, tags ...string) []map[string]interface{}

MapsDeep converts <i> to []map[string]interface{} recursively.

func Rune ¶

func Rune(i interface{}) rune

Rune converts <i> to rune.

func Runes ¶

func Runes(i interface{}) []rune

Runes converts <i> to []rune.

func SliceAny ¶

func SliceAny(i interface{}) []interface{}

SliceAny is alias of Interfaces.

func SliceFloat ¶

func SliceFloat(i interface{}) []float64

SliceFloat is alias of Floats.

func SliceInt ¶

func SliceInt(i interface{}) []int

SliceInt is alias of Ints.

func SliceMap ¶

func SliceMap(i interface{}) []map[string]interface{}

SliceMap is alias of Maps.

func SliceMapDeep ¶

func SliceMapDeep(i interface{}) []map[string]interface{}

SliceMapDeep is alias of MapsDeep.

func SliceStr ¶

func SliceStr(i interface{}) []string

SliceStr is alias of Strings.

func SliceStruct ¶

func SliceStruct(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

SliceStruct is alias of Structs.

func SliceStructDeep ¶

func SliceStructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) (err error)

SliceStructDeep is alias of StructsDeep.

func String ¶

func String(i interface{}) string

String converts <i> to string.

func Strings ¶

func Strings(i interface{}) []string

Strings converts <i> to []string.

func Struct ¶

func Struct(params interface{}, pointer interface{}, mapping ...map[string]string) error

Struct maps the params key-value pairs to the corresponding struct object's properties. The third parameter <mapping> is unnecessary, indicating the mapping rules between the custom key name and the attribute name(case sensitive).

Note:

1. The <params> can be any type of map/struct, usually a map.
2. The second parameter <pointer> should be a pointer to the struct object.
3. Only the public attributes of struct object can be mapped.
4. If <params> is a map, the key of the map <params> can be lowercase. It will automatically convert the first letter of the key to uppercase in mapping procedure to do the matching. It ignores the map key, if it does not match.

func StructDeep ¶

func StructDeep(params interface{}, pointer interface{}, mapping ...map[string]string) error

StructDeep do Struct function recursively. See Struct.

func Structs ¶
