Egypt ITIDA Generate eReceipt UUID

See more Egypt ITIDA Examples

Demonstrates how to generate the eReceipt UUID for Egypt ITIDA.

Note: This example requires Chilkat v9.5.0.92 or greater.

Rust

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: This example requires Chilkat v9.5.0.92 or greater.
// (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
let sb = chilkat::StringBuilder::new();

// Load the eReceipt JSON into a StringBuilder object.
if sb.load_file("qa_data/itida/EReceipt_ex.json", "utf-8").is_err() {
    println!("Failed to load input file.");
    return;
}

// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
let _ = sb.encode("itida", "utf-8");

// Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
// (always use utf-8)
let uuid = sb.get_hash("sha256", "hex_lower", "utf-8").unwrap_or_default();
println!("eInvoicing UUID = {}", uuid);
