@endragor, here it is. And it's not for network lib, it's from my new library `asyncstreams`. [https://github.com/vegansk/asyncstreams/blob/2dd997ea1ce5bc0b0d74783d1053da95d7f07cd0/src/asyncstreams.nim#L138](https://github.com/vegansk/asyncstreams/blob/2dd997ea1ce5bc0b0d74783d1053da95d7f07cd0/src/asyncstreams.nim#L138)
@Krux02, I'm not saying about strings. I'm sayin that I need the operations with `buf: pointer, size: int`. See previous example. @ka, thanks :)
