Struct Rule 

pub struct Rule {
    pub birth: u32,
    pub survive: u32,
    pub states: u32,
    pub neighbourhood: Neighbourhood,
}

One compiled rule, as the step shader reads it.

Fields

birth: u32

Bit k: a dead cell with k live neighbours is born.

survive: u32

Bit k: a live cell with k live neighbours stays live.

states: u32

Dead, live and the decay stages: 2..=MAX_STATES.

neighbourhood: Neighbourhood

Which cells are counted.

Implementations

impl Rule

pub fn inline( birth: &[i64], survive: &[i64], states: i64, neighbourhood: Neighbourhood, ) -> Result<Self, String>

An inline rule from its birth and survive counts, or the reason it is not one: a count past the neighbourhood’s max_count (or below zero), or states outside 2..=MAX_STATES.

Trait Implementations

impl Clone for Rule

fn clone(&self) -> Rule

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Rule

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Rule

fn eq(&self, other: &Rule) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Rule

impl Eq for Rule

impl StructuralPartialEq for Rule
