Function to_ac_ots_instance 

pub fn to_ac_ots_instance(
    module: &PioModule<PioValue>,
) -> Result<PioModule<AcOtsInstance>, Error>

Construct an AC optimal transmission switching calculation with the default switching options: every initially in-service branch may switch, at zero cost, with no budget, no islands, and no current limits, and the objective gains the switching cost term. The module holds a balanced network (the AC optimal power flow base is AcOpfInstance::from_network) or an AC optimal power flow calculation. An AC optimal transmission switching module comes back unchanged.

Errors

A value of another kind, or a base the defaults cannot build on.
