Trait ca_rules::ParseNtNeumann

pub trait ParseNtNeumann {
    fn from_bs(b: Vec<u8>, s: Vec<u8>) -> Self;

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

A trait for parsing non-totalistic 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::ParseNtNeumann;

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

impl ParseNtNeumann for Rule {
    fn from_bs(b: Vec<u8>, s: Vec<u8>) -> Self {
        Rule { b, s }
    }
}

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

assert!(life.s.contains(&0x00));

Required Methods

fn from_bs(b: Vec<u8>, s: Vec<u8>) -> Self

Construct the rule from b / s data.

Provided Methods

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

The parser.
