Method iterate

ciphercore-base/src/graphs.rs:3029–3031

Adds a node that iteratively computes a given finalized graph on the elements of a given vector and updates the state value accordingly. This node calls another `graph` with 2 input nodes `old_state` and `input` and an output node that returns a [tuple](Type::Tuple) `(new_state, output)`. This graph is used to map the elements of a given vector `V` to another vector `W` as follows: ```text graph(

(&self, graph: Graph, state: Node, input: Node)

    /// g2.iterate(g1, initial_state, input_vector).unwrap();
    /// ```
    pub fn iterate(&self, graph: Graph, state: Node, input: Node) -> Result<Node> {
        self.add_node(vec![state, input], vec![graph], Operation::Iterate)
    }

    /// Adds a node converting an array to a vector.
