WeightedChoiceNode

copperlace::render

Struct WeightedChoiceNode 

Source 
pub struct WeightedChoiceNode { /* private fields */ }
Expand description

Randomly renders one child node using per-child weights.

Weighted choices are produced from arrays containing at least one weighted object entry, such as { value = "common", weight = 9 }. Plain entries in the same array receive weight 1.0.

Implementations§

Source§

impl WeightedChoiceNode

Source

pub fn new( entries: Vec<(Box<dyn TextGeneratorNode>, f64)>, ) -> Result<Self, RenderError>
