Cannot use moved BufReader after for loop with bufreader.lines()

Question

I\'m trying to read some lines from a file, skipping the first few and printing the rest, but I keep getting errors about used value after move:

use std::fs:         


        

Answer 1

In order to avoid the move, use the Read::by_ref() method. That way, you only borrow the BufReader:

for (index, line) in buffer.by_ref().lines().enumerate() { ... }
//                         ^^^^^^^^^
// you can still use `buffer` here
