DHI XML

Rust community library for serializaing/deserializing TSYS DHI (Device Host Interface) XML messages.

Usage

rust use dhi_xml::{DHIRequest, DHIResponse};

DHI requests: ```rust // JSON payload (for example, from HTTP request) let iso_data = r#"{ "i000": "0100", "i002": "555544**0895", "i007": "Transmission date & time ", "i011": "STAN", "i012": "hhmmss", "i013": "MMDD", "i037": "Retrieval Reference Number" }"#;

// Deserializing request from the given JSON payload let r: DHIRequest = DHIRequest::new(serdejson::fromstr(&iso_data).unwrap());

// The data may now be accessed with asserteq!(r.isofields["i002"], "555544**0895");

// Serialization let msg = r.serialize().unwrap();

// The message may be sent through the TCP stream let s = TcpStream::connect(host); s.writeall(&msg.asbytes()); ```

DHI response: ```rust

let s = r##"
