Go で構造体のプロパティに動的にアクセスして変更するにはどうすればよいですか?

import (
    "errors"
    "fmt"
    "reflect"
)

func setField(v interface{}, name string, value string) error {
    // Ensure v is a pointer to a struct
    rv := reflect.ValueOf(v)
    if rv.Kind() != reflect.Ptr || rv.Elem().Kind() != reflect.Struct {
        return errors.New("v must be pointer to struct")
    }
    
    rv = rv.Elem() // Dereference pointer

    fv := rv.FieldByName(name) // Lookup field by name
    if !fv.IsValid() {
        return fmt.Errorf("not a field name: %s", name)
    }
    
    if !fv.CanSet() {
        return fmt.Errorf("cannot set field %s", name)
    }

    // Ensure we are setting a string field
    if fv.Kind() != reflect.String {
        return fmt.Errorf("%s is not a string field", name)
    }

    fv.SetString(value) // Set the value
    return nil
}

var config SshConfig
...

err := setField(&config, split[0], strings.Join(split[1:], " "))
if err != nil {
    // Handle error
}
