Struct DerivedSeriesEngine 

pub struct DerivedSeriesEngine { /* private fields */ }

Engine that evaluates derived series in topological order.

Evaluation Strategy

Definitions are topologically sorted into wave-front levels: nodes within the same level share no mutual dependencies and are evaluated in parallel via rayon. After each level completes, results are merged into the MultiSeriesContext so that the next level’s expressions can reference them.

Implementations

impl DerivedSeriesEngine

pub fn new(definitions: Vec<DerivedSeriesDefinition>) -> Self

Creates a new engine from the given definitions.

pub fn evaluate( &self, ctx: &mut MultiSeriesContext, ) -> Result<HashMap<String, Vec<f64>>, MultivariateError>

Topologically sort and evaluate all definitions.

Nodes within the same wave-front level are evaluated in parallel via rayon. Results are merged into the context after each level so that the next level’s expressions can reference them.
