yeah, I think the problem here is that to make up the struct, I need to read
bytes from the file..that's why the ` create_from_buff ` function.

r_std_hashmap/614907_12_0.txt | If you have to add ` String ` s at runtime, and maybe have different uses of `

and then use ` Vec<&'a str> ` and ` Hashmap<&'a str, usize> ` pointing into
it.
