Enum q1tsim::gates::Parameter

pub enum Parameter {
    Direct(f64),
    Reference(Rc<RefCell<f64>>, String),
    FFIRef(*const f64),
}

Enumeration for parameters (usually angles) to a gate. This can either be a direct floating points value, or a reference to one. In the latter case, the value of the parameter can be changed outside the circuit, which can be useful to e.g. to reexecute a circuit with the end state of the last excution, but with a different value for a parameter. For reference parameters, a name is associated with the parameter for the description, since its value can change.

Variants

Direct(f64)

Direct value

Reference(Rc<RefCell<f64>>, String)

Reference value, mutable outside the circuit, with its name

FFIRef(*const f64)

Reference parameter from external code
