Struct BiomeStats 

pub struct BiomeStats {
    pub counts: [usize; 20],
    pub total: usize,
}

Statistics about biome distribution in a region.

Fields

counts: [usize; 20]

Count of each biome type (indexed by BiomeType as usize).

total: usize

Total cells counted.

Implementations

impl BiomeStats

pub fn from_map(bm: &BiomeMap) -> Self

Compute biome statistics from a BiomeMap.

pub fn fraction(&self, biome: BiomeType) -> f32

Fraction of the map covered by a given biome (0..1).

pub fn dominant_biome(&self) -> BiomeType

Most common biome.

pub fn sorted_biomes(&self) -> Vec<(BiomeType, usize)>

Biomes sorted by prevalence (most common first).

pub fn diversity_index(&self) -> f32

Biome diversity index (Shannon entropy, normalized).

Trait Implementations

impl Clone for BiomeStats

fn clone(&self) -> BiomeStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BiomeStats

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

Formats the value using the given formatter.

impl Default for BiomeStats

fn default() -> BiomeStats

Returns the “default value” for a type.
