line-numbers 
line-numbers is a Rust crate for efficiently finding the line number of a string offset.
Usage
Create a LinePositions, then you can find line numbers for an
offset.
let s = "foo\nbar\nbaz\n";
let s_lines: Vec<_> = s.lines().collect();
let line_positions = LinePositions::from(s);
let offset = 5;
let (line_num, column) = line_positions.from_offset(offset);
println!(
"Offset {} is on line {} (column {}), and the text of that line is {:?}.",
offset,
line_num.display(),
column,
s_lines[line_num.as_usize()]
);
