ChoiceNode

copperlace::render

Struct ChoiceNode 

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

Randomly renders one child node from a list of alternatives.

This is produced from text-rendered config arrays. For example, mood = [happy, sad] becomes a choice between two literal nodes. If the array is empty, rendering returns RenderError::EmptyChoice.
