In go, you can do mmap with some help of external library :) you can mmap a file - https://github.com/edsrzf/mmap-go - and then unsafe-retype that to slice of objects, and then read/write to it. It's very handy sometimes! It's unsafe though. You also need to be careful to not have any pointers in the struct (so also no slices, maps); or if you have pointers, the must be nil. Once you start unsafe-retyping random bytes to pointers, thing explode very quickly. So maybe this article has a point. |
