Implementations

impl Crowd

pub fn count(&self) -> usize

Number of characters in the crowd.

pub fn get(&self, id: usize) -> Option<&CrowdCharacter>

Look up a character by id.

pub fn mean_params(&self) -> HashMap<String, f32>

Compute the mean value of each parameter across the crowd.

pub fn std_params(&self) -> HashMap<String, f32>

Compute the standard deviation of each parameter across the crowd.

pub fn diversity_score(&self) -> f32

Mean pairwise parameter distance (diversity score).

pub fn by_class(&self, class: &VariationClass) -> Vec<&CrowdCharacter>

Return all characters that belong to the given VariationClass.

pub fn class_distribution(&self) -> HashMap<VariationClass, usize>

Count characters per variation class.

pub fn sorted_by(&self, param: &str) -> Vec<&CrowdCharacter>

Return references to characters sorted in ascending order by param.

Characters missing the requested parameter are placed at the end.

pub fn to_param_list(&self) -> Vec<HashMap<String, f32>>

Export the crowd as a plain list of param maps (for batch processing).

pub fn summary(&self) -> String

Generate a JSON-like human-readable summary string.
