Function join_circuits_seq 

pub fn join_circuits_seq<T>(
    seq: impl IntoIterator<Item = (Circuit<T>, impl IntoIterator<Item = Option<(T, bool)>>)>,
    last: Circuit<T>,
) -> Circuit<T>
where
    T: Clone + Copy + Ord + PartialEq + Eq + Debug + Default + TryFrom<usize>,
    <T as TryFrom<usize>>::Error: Debug,
    usize: TryFrom<T>,
    <usize as TryFrom<T>>::Error: Debug,

Join multiple circuits sequentially.

A seq is iterator of entries of structure with fields:

1. The circuit to join.
2. List of connections between current circuit outputs and next (from next entry or last) circuit inputs. List entry index is next circuit input index. Value is option of tuple of index of output from some previous circuit and negation of that output. This index of output is index of all list circuit output from first circuit to current circuit (from current entry). This index starts from 0.

Any not connected circuit input will be added as input to final circuit. Any not connected circuit output will be added as output to final circuit. Function returns join of all circuits.

Example with description of structure data:

    join_circuits_seq(

                // connect negated first circuit output 1 to second circuit input 1.
                // connect negated first circuit output 4 to second circuit input 2.
