Struct ZoneStats 

pub struct ZoneStats {
    pub heat: f32,
    pub density: f32,
    pub cooldown: u32,
    pub changed_count: usize,
    pub last_injection_generation: u64,
}

Statistics for a single zone in the life field.

Fields

heat: f32

Heat value representing recent activity (decays over time).

density: f32

Current cell density in this zone (0.0-1.0).

cooldown: u32

Cooldown counter preventing immediate re-injection.

changed_count: usize

Count of cells that changed this generation.

last_injection_generation: u64

Generation when this zone was last injected (0 = never).

Implementations

impl ZoneStats

pub fn record_change(&mut self)

Records a cell change in this zone.

pub fn decay_heat(&mut self, decay: f32)

Decays the heat value by the given factor.

pub fn update_density(&mut self, alive: usize, total: usize)

Updates the density value.

pub fn is_cool(&self) -> bool

Returns true if the zone is cool (no cooldown active).

pub fn tick_cooldown(&mut self)

Decrements cooldown if active.

pub fn set_cooldown(&mut self, min: u32, max: u32, rng: &mut impl Rng)

Sets cooldown to a random value between min and max.

pub fn reset_changed(&mut self)

Resets the changed count for a new generation.

pub fn add_heat(&mut self, amount: f32)

Adds heat to the zone (e.g., from activity).

pub fn is_on_cooldown(&self) -> bool

Check if zone is on cooldown

pub fn is_cold_empty(&self) -> bool

Check if zone is cold (low heat) and empty (very low density)

pub fn is_cold_ash(&self) -> bool

Check if zone is cold (low heat) and has ash/debris (moderate density)

Trait Implementations

impl Clone for ZoneStats

fn clone(&self) -> ZoneStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ZoneStats

impl Debug for ZoneStats

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

Formats the value using the given formatter.

impl Default for ZoneStats

fn default() -> ZoneStats

Returns the “default value” for a type.
