CA formats parsers

Travis (.com) Crates.io Docs.rs 中文

Parsing pattern files for Conway's Game of Life.

The parsers read a string and return an iterator of coordinates of living cells.

Supported formats

Example

```rust use ca_formats::rle::Rle;

const GLIDER: &str = r"#N Glider

let glider = Rle::new(GLIDER).unwrap(); asserteq!(glider.headerdata().unwrap().x, 3); asserteq!(glider.headerdata().unwrap().y, 3); asserteq!(glider.headerdata().unwrap().rule, Some(String::from("B3/S23")));

let cells = glider.map(|cell| cell.unwrap().position).collect::>(); assert_eq!(cells, vec![(1, 0), (2, 1), (0, 2), (1, 2), (2, 2)]); ```
