Struct Evaluator

pub struct Evaluator {
    pub amplitudes: Vec<Box<dyn Amplitude>>,
    pub resources: Arc<RwLock<Resources>>,
    pub dataset: Arc<Dataset>,
    pub expression: Expression,
}

A structure which can be used to evaluate the stored Expression built on registered Amplitudes. This contains a Resources struct which already contains cached values for precomputed Amplitudes and any relevant free parameters and constants.

Fields

amplitudes: Vec<Box<dyn Amplitude>>

A list of Amplitudes which were registered with the Manager used to create the internal Expression. This includes but is not limited to those which are actually used in the Expression.

resources: Arc<RwLock<Resources>>

The internal Resources where precalculated values are stored

dataset: Arc<Dataset>

The internal Dataset

expression: Expression

The internal Expression
