Struct QuantumOperatorPlan 

pub struct QuantumOperatorPlan { /* private fields */ }

Fixed-pattern materialization of a QuantumOperator.

Construction aligns every component with the union sparsity pattern once. Subsequent evaluations update only numerical values, preserving the sparse indices and any backend analysis that depends on them.

Implementations

impl QuantumOperatorPlan

pub fn component_names(&self) -> impl Iterator<Item = &str>

Iterate component names in the coefficient order accepted by the plan.

pub fn operator(&self) -> &Operator

Borrow the most recently evaluated operator and its stable storage.

pub fn resolve_coefficients( &self, parameters: &HashMap<String, Complex64>, ) -> Result<Vec<Complex64>>

Resolve a parameter map into the plan’s stable coefficient order.

pub fn evaluate( &mut self, parameters: &HashMap<String, Complex64>, ) -> Result<&Operator>

Evaluate named parameters while reusing the plan’s storage pattern.

pub fn evaluate_coefficients( &mut self, coefficients: &[Complex64], ) -> Result<&Operator>

Evaluate coefficients already arranged in Self::component_names order.

This is the lowest-overhead scan path: it performs no name lookup and allocates no matrix structure.
