Load a huge file into a byte slice without actually reading any data.
go get -u github.com/tidwall/mmap
Load a bigole file into a byte slice. This happens pretty much instantly even if your file is many GBs.
data, err := mmap.Open("my-big-file.txt")
if err != nil {
panic(err)
}
Now you can read the data
slice like any other Go slice.
Make sure to release the data when your done.
mmap.Close(data)
Don't read the data
after closing otherwise your f*cked.
That's all, bye now
