Savesys

A simple, expandable, variable-based save system.

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

Functions

• generate(SAVE_NAME: &'static str, num: i32) is self-explanatory.
• exists(SAVE_NAME: &'static str) checks to see if the SAVE_NAME exists and returns the corresponding boolean.
• reader(SAVE_NAME: &'static str) scans SAVE_NAME and returns the values per line into a Vec.
• writer(SAVE_NAME: &'static str, line: usize, state: i32) scans the line and new number passed in, and writes to SAVE_NAME.

Example Usage

extern crate savesys;
use savesys::*;

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

let save_vec: Vec<i32> = savesys::reader("data.txt");
if ! save_vec[5] == 7 { writer("data.txt", 5, 7) }
