Implementations

impl ExpressionNode

pub fn evaluate(&self, amplitude_values: &[Complex64]) -> Complex64

Evaluate an ExpressionNode over a single event using calculated AmplitudeValues

This method parses the underlying ExpressionNode but doesn’t actually calculate the values from the Amplitudes themselves.

pub fn evaluate_gradient( &self, amplitude_values: &[Complex64], gradient_values: &[DVector<Complex64>], ) -> DVector<Complex64>

Evaluate the gradient of an ExpressionNode over a single event using calculated AmplitudeValues

This method parses the underlying ExpressionNode but doesn’t actually calculate the gradient from the Amplitudes themselves.

Trait Implementations

impl Clone for ExpressionNode

fn clone(&self) -> ExpressionNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExpressionNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ExpressionNode

fn default() -> ExpressionNode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ExpressionNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
