WeightedTable

polydat_nodes::probability

Struct WeightedTable 

Source 
pub struct WeightedTable {
    pub values: Vec<String>,
    pub cumulative: Vec<f64>,
}
Expand description

Pre-parsed value table for one_of_weighted. The cumulative vector is normalised so the last entry is exactly 1.0, letting the eval body locate the matching bucket with a single binary search.

Fields§

§values: Vec<String>

Output values in declaration order.

§cumulative: Vec<f64>

Cumulative weights, normalised to [0.0, 1.0]. The last entry is always 1.0.

Implementations§

Source§

impl WeightedTable

Source

pub fn parse(spec: &str) -> Self

Single-call setup. The #[polydat_node] macro invokes this exactly once in the generated OneOfWeighted::new(). Panics on a malformed spec.
