Rust client for NVI / KPS identity verification — async, small and production-oriented.

nvi_rs is a lightweight Rust library that helps interacting with the Turkish NVI/KPS SOAP identity verification services. It includes helpers to build SOAP requests, obtain WS-Trust (STS) tokens, sign requests when required, and parse responses into ergonomic Rust types.

• Async API (tokio + reqwest)
• WS-Trust (STS) token acquisition
• Small, robust XML helpers (quick-xml)
• Enterprise-style constants exposed in crate::constants

The example uses an optional .env file (loaded with dotenvy) so you can run it the same way on Windows, macOS and Linux.

Create a .env file in the project root with the following (optional) values:

KPS_USERNAME=your-username
KPS_PASSWORD=your-password

Then run the example from the project root with a single command:

cargo run --example basic

This approach avoids OS-specific environment commands and works cross-platform.

1. Install Rust (rustup) — https://rustup.rs
2. (Optional) Create a .env with credentials as shown above.
3. Run the example:

cargo run --example basic

Run the full test suite (includes an integration test that uses wiremock):

cargo test --workspace --verbose
