Types

type Var

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

Var is an universal variable type.

func New

func New(value interface{}, safe ...bool) *Var

New returns a new Var with given <value>. The parameter <safe> used to specify whether using Var in concurrent-safety, which is false in default.

func (*Var) Array

func (v *Var) Array() []interface{}

Array is alias of Interfaces.

func (*Var) Bool

func (v *Var) Bool() bool

Bool converts and returns <v> as bool.

func (*Var) Bytes

func (v *Var) Bytes() []byte

Bytes converts and returns <v> as []byte.

func (*Var) Duration

func (v *Var) Duration() time.Duration

Duration converts and returns <v> as time.Duration. If value of <v> is string, then it uses time.ParseDuration for conversion.

func (v *Var) Int32() int32

Int32 converts and returns <v> as int32.

func (*Var) Int64

func (v *Var) Int64() int64

Int64 converts and returns <v> as int64.

func (*Var) Int8

func (v *Var) Int8() int8

Int8 converts and returns <v> as int8.

func (*Var) Interface

func (v *Var) Interface() interface{}

Interface is alias of Val.

func (*Var) Interfaces

func (v *Var) Interfaces() []interface{}

Interfaces converts and returns <v> as []interfaces{}.

func (*Var) Ints

func (v *Var) Ints() []int

Ints converts and returns <v> as []int.

func (*Var) IsEmpty

func (v *Var) IsEmpty() bool

IsEmpty checks whether <v> is empty.

func (*Var) IsNil

func (v *Var) IsNil() bool

IsNil checks whether <v> is nil.

func (*Var) Map

func (v *Var) Map(tags ...string) map[string]interface{}

Map converts <v> to map[string]interface{}.

MapStrStr converts <v> to map[string]string.

func (*Var) MapStrStrDeep

func (v *Var) MapStrStrDeep(tags ...string) map[string]string

MapDeep converts <v> to map[string]string recursively.

func (*Var) MapStrVar

func (v *Var) MapStrVar(tags ...string) map[string]*Var

MapStrVar converts <v> to map[string]*Var.

func (v *Var) MapStrVarDeep(tags ...string) map[string]*Var

MapStrVarDeep converts <v> to map[string]*Var recursively.

func (*Var) MapToMap

func (v *Var) MapToMap(pointer interface{}, mapping ...map[string]string) (err error)

MapToMap converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of struct/*struct.

func (*Var) MapToMapDeep

func (v *Var) MapToMapDeep(pointer interface{}, mapping ...map[string]string) (err error)

MapToMapDeep recursively converts map type variable <params> to another map type variable <pointer>. The elements of <pointer> should be type of struct/*struct.

func (*Var) MapToMaps
