Enum VariationalPattern 

pub enum VariationalPattern {
    SingleRotation {
        axis: char,
        param: Expression,
    },
    EntanglingLayer {
        params: Vec<Expression>,
    },
    VqeAnsatz {
        params: Vec<Expression>,
    },
    QaoaMixer {
        beta: Expression,
    },
    QaoaCost {
        gamma: Expression,
    },
}

Recognize variational quantum circuit parameter patterns.

VariationalPattern::SingleRotation, VariationalPattern::QaoaMixer and VariationalPattern::QaoaCost are constructible from a single gate expression and are produced by recognize_variational_pattern.

VariationalPattern::EntanglingLayer and VariationalPattern::VqeAnsatz are forward-declared scaffolding for a future circuit-level pattern API: recognizing an entangling layer or a full VQE ansatz genuinely requires looking at a sequence of gates (e.g. the CNOT/CZ ladder plus the per-qubit rotations that make up one ansatz layer), which cannot be read off a single Expression. No function in this crate constructs these two variants today; they exist purely as planned enum shape for when a multi-gate (&[Expression]-based) recognizer is added.
