Enum RosterRule 

pub enum RosterRule {
    R445,
    Amoeba,
    Builder,
    Clouds,
    Coral,
    Crystal,
    Pyroclastic,
    SlowDecay,
}

The closed roster of named rules. Each entry’s notation in the comment is survive/birth/states/neighbourhood, as the 3D automaton catalogues write it; every one is held by every_roster_rule_lives_from_its_own_seed to a live fraction strictly inside (0, 0.9) at generations 100 and 400.

Variants

R445

4/4/5/M: a sparse ball that burns out to a few still cells.

Amoeba

9-26/5-7,12-13,15/5/M: a sparse field that swells into a mass filling most of the cube.

Builder

2,6,9/4,6,8-9/10/M: a burst of long-decaying growth that leaves a still scatter of cells behind.

Clouds

13-26/13-14,17-19/2/M: a dense field that settles into rounded clouds.

Coral

5-8/6-7,9,12/4/M: a slowly churning reef with a skin of decaying cells.

Crystal

0-6/1,3/2/VN: a small seed growing into a lattice that fills most of the cube.

Pyroclastic

4-7/6-8/10/M: a restless, never-settling foam of cells and long decay.

SlowDecay

1,4,8,11,13-26/13-26/5/M: a dense field that freezes almost at once.

Implementations

impl RosterRule

pub const ALL: [RosterRule; 8]

Every roster rule, in the order the generated reference lists them.

pub fn from_name(name: &str) -> Option<Self>

Parse a roster name, or None.

pub fn as_str(self) -> &'static str

The name a preset writes — from_name’s inverse.

pub fn seed(self) -> (f32, f32)

The seed this rule lives from, as (seed_radius, seed_fill): what an absent [voxel] seed_radius and seed_fill mean when the list opens with this rule. A 3D rule is particular about its seed — clouds survives only a dense field and dies from a sparse one, where crystal grows from a small sparse ball.

pub fn rule(self) -> Rule

The compiled rule.

Trait Implementations

impl Clone for RosterRule

fn clone(&self) -> RosterRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RosterRule

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

Formats the value using the given formatter.

impl PartialEq for RosterRule

fn eq(&self, other: &RosterRule) -> 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.
