Savesys

A simple, expandable, variable-based save system.

Forked from the save system used in my other project, The Plains.

Purpose

Savesys uses an external text file for managing variables. It's called by a couple commands that create files that you can later reference.

Functions

• generate(SAVE_NAME: &'static str, num: i32) is used to generate the save file.
• exists(SAVE_NAME: &'static str) checks to see if the file exists and returns a corresponding boolean.
• reader(SAVE_NAME: &'static str) scans SAVE_NAME and returns the numbers from the file into a Vec.
• writer(SAVE_NAME: &'static str, line: usize, state: i32) scans the line and new number you pass in, and writes to the file.

Example Usage

``` extern crate savesys; use savesys::*;

if exists("data.txt") == false { generate("data.txt", 20) };

writer("data.txt", 5, 7);

let save_vec: Vec = savesys::reader("data.txt"); ```
