Enum SwitchTreatment 

pub enum SwitchTreatment {
    Merge,
    Regularize,
    Constrain,
}

What a retained switch becomes in the solver’s equations.

Variants

Merge

Not represented at all. Only valid when nothing was retained — a retained switch under Merge would be silently dropped, which is worse than refusing.

Regularize

A stiff branch, at the same magnitude topology::IDEAL_CONNECTION_Y gives a merged zero-impedance connection.

Constrain

An exact equality: θ_i = θ_j, V_i = V_j, with the switch’s flow as an unknown. No admittance, and no constant to choose.

Solved by constrained::solve_constrained rather than by the ordinary Newton loop, since the system it builds is a KKT system rather than a power-flow Jacobian. A network built under this treatment therefore carries no switch branches at all — see NodeBreakerNetwork::constrained_switches.
