Function circuit_description_and_inputs 

pub fn circuit_description_and_inputs(
    is_mask: bool,
    image_bytes: Option<Vec<u8>>,
) -> Result<Circuit<Fr>>

Return the circuit description, and inputs for the iris code circuit, in either the mask (true) or iris (false) case. If image_bytes is None, the default test image is used.

Example:

use frontend::zk_iriscode_ss::v3::circuit_description_and_inputs;
let circuit_result = circuit_description_and_inputs(false, None);
