Trait ca_rules::ParseNtNeumannGen

pub trait ParseNtNeumannGen {
    fn from_bsg(b: Vec<u8>, s: Vec<u8>, gen: usize) -> Self;

    fn parse_rule(input: &str) -> Result<Self, ParseRuleError>
    where
        Self: Sized,
    { ... }
}

A trait for parsing non-totalistic Generations rules with von Neumann neighborhood. Both isotropic and non-isotropic rules are supported.

The b / s data of this type of rules consists of possible combinations of states of the 4 neighbors, represented by an 8-bit binary number, that cause a cell to be born / survive.

For example, the following neighborhood is represented by the number 10 = 0b1010:

  1
0 _ 1
  0

Examples

use ca_rules::ParseNtNeumannGen;

#[derive(Debug, Eq, PartialEq)]
struct Rule {
    b: Vec<u8>,
    s: Vec<u8>,
    gen: usize,
}

impl ParseNtNeumannGen for Rule {
    fn from_bsg(b: Vec<u8>, s: Vec<u8>, gen: usize) -> Self {
        Rule { b, s, gen }
    }
}

let life = Rule::parse_rule("MAPHmlphg/3").unwrap();

assert_eq!(life.gen, 3);

Required methods

fn from_bsg(b: Vec<u8>, s: Vec<u8>, gen: usize) -> Self
