Functions ¶

func AssertType ¶ added in v0.0.34

func AssertType[T any](v any) (T, bool)

func CanCast ¶ added in v0.0.34

func CanCast[T any](v any) bool

func CanElem ¶ added in v0.0.24

func CanElem(k reflect.Kind) bool

func Clone ¶ added in v0.0.26

func Clone[T any](src T) (dst T)

func DeepCopy ¶ added in v0.0.26

func DeepCopy(v, x reflect.Value)

func HackField ¶ added in v0.0.32

func HackField(v any, i int) reflect.Value

func HackFieldByName ¶ added in v0.0.32

func HackFieldByName(v any, name string) reflect.Value

func Indirect ¶

func Indirect(v any) reflect.Value

Indirect deref all level pointer references

func IndirectNew ¶

func IndirectNew(v any) reflect.Value

IndirectNew returns the indirect value of v this function is safe and WILL NOT trigger panic. if the input is invalid, InvalidValue returns. validation of return is recommended.

func IsBytes ¶

func IsBytes(v any) bool

func IsFloat ¶

func IsFloat(v any) bool

func IsInteger ¶

func IsInteger(v any) bool

func IsNumeric ¶

func IsNumeric(v any) bool

func IsZero ¶

func IsZero(v any) bool

IsZero checks whether the given value is zero or its underlying value is zero

If the value implements the ZeroChecker interface, IsZero will use its IsZero method to determine zero-ness. Special handling is provided for slices, maps, strings, and channels, which are considered zero if their length is zero.

func MustAssertType ¶ added in v0.0.34

func MustAssertType[T any](v any) T

func New ¶

func New(t reflect.Type) reflect.Value

New a `reflect.Value` with reflect.Type not like reflect.New, but new all level pointer ref

func NewElem ¶

func NewElem(t reflect.Type) reflect.Value

NewElem new the indirect type of t

func Typename ¶

func Typename(rt reflect.Type) string

Typename returns the full type name of rt

Types ¶

type Flag ¶ added in v0.1.0

type Flag struct {
	Name    string
	Options [][2]string
}

Flag represents a single tag value with optional key-value options. For example, the tag `name:"field,opt1,opt2=v2"` will be parsed into: {Name: "field", Options: [][2]string{{"opt1": ""}, {"opt2": "v2"}}}

func (Flag) TagValue ¶ added in v0.1.0

func (f Flag) TagValue() string

type Flags ¶ added in v0.1.0

type Flags map[string]*Flag

func ParseFlags ¶ added in v0.1.0

func ParseFlags(tag reflect.StructTag) Flags

ParseFlags parses struct tag annotations into a structured Flags map. It supports tag formats like: `key:"value,opt1,opt2=v2"`. Each key-value pair in the tag is processed into a Flag with Value and Options. Conflicting tags (i.e., duplicate keys) will be detected and removed. The function also handles quoted values and options with or without values.

func (Flags) Get ¶ added in v0.1.0

func (fs Flags) Get(key string) *Flag

type ZeroChecker ¶ added in v0.1.0

type ZeroChecker interface {
	IsZero() bool
}
