Functions

func Copy

func Copy(src interface{}, dst interface{}) (err error)

Copy copies fields from src to dst using reflection. Supports struct-to-struct and slice-to-slice copying.

func FieldNames

func FieldNames(s interface{}) []string

FieldNames returns all field names of a struct.

func IsPtrSlice

func IsPtrSlice(v reflect.Value) bool

IsPtrSlice returns true if v is a pointer to a slice.

func IsSliceOfPtr

func IsSliceOfPtr(slice reflect.Value) bool

IsSliceOfPtr returns true if the slice contains pointers.

func IsZero

func IsZero(v reflect.Value) bool

IsZero returns true if the value is the zero value for its type.

func SetField

func SetField(ps reflect.Value, name string, value interface{}) error

SetField sets a field on an addressable struct by name.

Types

type Type

type Type = reflect.Type

Type aliases reflect.Type.
