File To Map

A small parser for using data from a file as a map.

This tool is best for programs that reading configuration in run-time but can be used for any data.

Example

configuration.txt

width=1920
height=1080

code.rs

use file_to_map::FileToMap;
fn main() {
	let file_to_map = FileToMap::new("configuration.txt").build().unwrap();
	let width: i32 = file_to_map.get("width").unwrap().parse::<i32>().unwrap();
	let height: i32 = file_to_map["height"].parse::<i32>().unwrap();
	println!("{], {}", width, height);
}

The default separator between key and value is =, but it is possible to change it:

let file_to_map = FileToMap::new("configuration.txt").build().unwrap();
file_to_map.set_key_value_separator("*").build().unwrap();

The default separator between pairs is a new line, but it is possible to change it:

let file_to_map = FileToMap::new("configuration.txt").build().unwrap();
file_to_map.set_pair_separator(",").build().unwrap();

More examples can be found in the tests directory.
