Overview ¶
Package conv 提供了基础的类型转换功能
会尽最大可能地将当前的值转换成指定类型的值。
conv.MustInt("123", 0) // 返回 123 的数值
conv.MustString(123, "")// 返回字符串 123
conv.Int("123", 0) // 返回 123 数值和 nil 的 error 接口
v := 5
conv.Value("3", reflect.ValueOf(v)) // 将 3 转换成数值,并写入 v 中。

Functions ¶
func Bool ¶
Bool 将 val 转换成 bool 类型或是在无法转换的情况下返回 error
以下值被可以被正确转换：
123(true), 0(false),"-123"(true), "on"(true), "off"(false), "true"(true), "false"(false)
func Map2Obj ¶
func Map2Obj(src any, dest any, conv FieldConvert) error
Map2Obj 将 map 中的数据转换成一个结构中的数据
func MustFloat32 ¶
MustFloat32 将 val 转换成 float32 类型或是在无法转换的情况下返回 def 参数
func MustFloat64 ¶
MustFloat64 将 val 转换成 float64 类型或是在无法转换的情况下返回 def 参数
func MustSliceOf ¶ added in v1.3.0
MustSliceOf 将 val 转换成 slice 类型或是在无法转换的情况下返回 def 参数
func MustString ¶
MustString 将 val 转换成 string 类型或是在无法转换的情况下返回 def 参数
func MustUint32 ¶
MustUint32 将 val 转换成 uint32 类型或是在无法转换的情况下返回 def 参数
func MustUint64 ¶
MustUint64 将 val 转换成 uint64 类型或是在无法转换的情况下返回 def 参数
func MustUintOf ¶ added in v1.3.0
MustUintOf 将 val 转换成 T 类型或是在无法转换的情况下返回 def 参数
func Obj2Map ¶
func Obj2Map(obj any, conv FieldConvert) (map[string]any, error)
Obj2Map 将 obj 转换成 map
NOTE: 只能转换可导出的数据。
func Slice ¶
Slice 将 val 转换成 slice 类型或是在无法转换的情况下返回 error
[]int, []interface{} 以及数组都可以转换。 []byte("123") 返回 []interface{}{byte(49),byte(50),byte(51)} "123" 返回 []interface{}{rune(49),rune(50),rune(51)}
func String ¶
String 将 val 转换成 string 类型或是在无法转换的情况下返回 error
NOTE: fmt.Stringer, ret.Error 和 encoding.TextMarshaler 都将被正确转换成字符串。
func Value ¶
Value 将 source 的值保存到成 target 中
如果 source 为 nil，则会将 target 的值设置为其默认的零值。
若类型不能直接转换，会尝试其它种方式转换，比如 strconv.ParseInt 等。
