Ну я естественно не массив интерфейсов передавал а интерфейс. Потому что с массивами своя беда там)
Akim
нет, объявление
Я еще вот к чему пришел

Кажется что interface{} это уже ссылка

нет, просто разыменовал указатель и получил обратно интерфейс

Кто знает, как постоянно получать сообщения от почты?
Sharifzoda
Нет, по imap протоколу
Sharifzoda
Получаю последнюю по индексу или список и т.д, но хочу как сервак постоянно получать, в реальном времени
Sharifzoda
Можете помочь?
Илья
Может другие подскажут, работал с почтой только на отправку
Sharifzoda
Аа, ок, спасибо за отзыв)
Akim

Ух, до меня с трудом дошло что интерфейс это отдельный тип и он никак не связан с наследованием.
Очень помог первый ответ.

Илья
интерфейс внутри это указатель на твой тип и описание твоего типа
Akim
Ага, это такая сложная умная магическая структура

anyone knows what's the fastest way to "serialize" a golang byte array and transfer over the wire?
faster than msgpack/json. faster than gob? no need to "serialize" as in... [][]byte <- or a way to quickly "pack" it for transfer.
i'm using redis pub/sub transfer protocol so need a way to serialize with least mem alloc and fastest way.
suggestions / feedback appreciated.

i'm looking for the
1. fastest way to serialize and unserialize [][]byte golang
or
2. the best zero alloc method to serialize and unserialize [][]byte golang
Melbourne Channel

not json data. just [][]byte.
kostyaBro
what to serialize the bytes for transmission, I don't understand you.
Just send them away by tcp
Melbourne Channel
what's tsp?

i've checked this but i was wondering what's the fastest way just to send [][]byte <- through redis pub/sub that's all. fastest / least mem alloc way
Melbourne Channel

yes but i needed the pub/sub feature. so i need to send through redis.
kostyaBro
yes but i needed the pub/sub feature. so i need to send through redis.
I don't understand why you can't just send bytes.
That u want from serialization
Melbourne Channel
it's [][]byte <- bytes array
Melbourne Channel
in that case, how do u serialize [][]bytes array into []bytes? :)
Melbourne Channel
fastest and least mem alloc way :D
kostyaBro
U need to allocate memory 1 time and replace data
kostyaBro
Your data in the [][]byte in some places in the memory.
If u want to replace data in one place, just use make and copy
Melbourne Channel
how do u serialize [][]bytes array into []bytes?
kostyaBro
.......
Melbourne Channel
this is how i do it.
any guys with better, fastest or least mem alloc way
func InterfaceToBytes(key interface{}) ([]byte, error) {
var buf bytes.Buffer
enc := gob.NewEncoder(&buf)
err := enc.Encode(key)
if err != nil {
return nil, err
}
return buf.Bytes(), nil
}
func BytesToInterface(bts []byte, data interface{}) error {
buf := bytes.NewBuffer(bts)
dec := gob.NewDecoder(buf)
err := dec.Decode(data)
if err != nil {
return err
}
return nil
}
kostyaBro
Create bytes slice using make
Use copy for each byte areay
Melbourne Channel

can u show the code for making [][]byte into []byte and reverse?
Oleg

I am a little bit confused. Can you explain again , is your problem about interface{} <-> []byte or [][]byte<-> []byte ?
Melbourne Channel
[][]byte to []byte <- i'm looking for the fastest or least mem alloc way to do so. the one i've shown is using gob and i think can be faster.
Oleg
kostyaBro
???

Νο.
I can't now.
And it is default syntax of golang.
1. Find sum of length of your [][]byte.
2. Use make for allocate expected capacity.
3. Use copy for replace bytes into new array
kostyaBro
Just rewrite this on go👆

The least mem alloc way is to calculate total size of data stored in [][]byte, then create []byte of required capacity
kostyaBro
1 alloc
Oleg
u hv solution?
I can’t give you a zero alloc options.
I think that iteration over [][]byte and copy to result array is not that bad solution
Melbourne Channel

yup. this seems like the "solution" :)
Oleg
Example
1. Calculate length of your result slice
2. Make result slice
3. Iterate over origin slice and copy it’s parts into result
