Scanner to read file from the end

• backscanner

  1 59 4.0 Go

  A scanner similar to bufio.Scanner, but it reads and returns lines in reverse order, starting at a given position and going backward.

A while back, I had this task of reading a file backward, line by line, to find a particular value. There is no solution in std lib. So, I tried to use some existent solution from github, like backscanner. But you know what? After wrestling with some tricky corner cases and realising it didn't quite fit my needs, I rolled up my sleeves and came up with my own solution. And just last week, I decided to built a highly effective reverse scanner - rscanner. I tried to cover all those corner cases, made interface similar to bufio.Scanner and kept it effective. Any thoughts or feedback are welcome!

  Same as bufio.Scanner, but in reverse. It enables scanning from the end to the beginning.
