HTTP Service in Rust to convert HTML to PDF

PDF-report generator in Rust

It is built in Rust using the following crates:

1. Rocket framework as HTTP Server
2. Handlebars-rust as template engine
3. wkhtmltopdf command line tool to generate PDF (not a crate)
4. Utilities: log, rust-ini, uuid

Application workflow is an synchronous call over HTTP and looks like this:

HTTP Route -> Service -> Template Engine -> wkhtmltopdf - PDF

See report template in templates/book-order-report.html.

Sample JSON request looks like this:

{
  "template_name": "book-order-report",
  "user_params": {
    "customer_name": "Frank Smith",
    "address": "Address: Frankfurt am Main, Mainzer str. 100",
    "ordered_books": [
