Usage

Basic APDU Transmission

fn main() {
    use iso7816_tx::TransmissionBuilder;

    let mut buf = [0u8; 258];
    let mut t = TransmissionBuilder::new()
        .set_init_cb(open)

        .set_write_cb(write)
        .set_sleep_cb(sleep)
        .set_nad(15, 51)
        .build();

    let atr = t.atr().expect("Failed to get ATR");

    let capdu = &[0x80, 0xca, 0x9f, 0x7f];
    let rapdu = t.transmit(capdu, &mut buf).expect("Failed to transmit");
}
