Functions

func FilterStruct

func FilterStruct[T any](input T, includeFields, excludeFields []string) (T, error)

FilterStruct filters the struct based on include and exclude fields and returns a new struct. - input: the original struct. - includeFields: list of fields to include (if empty, includes all). - excludeFields: list of fields to exclude (processed after include).

func GetStructFields

func GetStructFields[T any](input T) ([]string, error)

GetStructFields returns all the top-level field names from the given struct. - input: the original struct. Returns a slice of field names or an error if the input is not a struct.

func Walk

func Walk(s interface{}, callback CallbackFunc)

Walk traverses a struct and executes a callback function on each field in the struct. The interface{} passed to the function should be a pointer to a struct

Types

type CallbackFunc

type CallbackFunc func(reflect.Value, reflect.StructField)

CallbackFunc on the struct field example: structValue := reflect.ValueOf(s) ... field := structValue.Field(i) fieldType := structValue.Type().Field(i)
