//! Native rust database driver for SAP HANA(TM).
//!
//! `hdbconnect` uses [`serde_db`](https://docs.rs/serde_db)
//! to simplify the data exchange between application code
//! and the driver, both for input parameters to prepared statements
//! and for results that are returned from the database.
//! There is no need to iterate over a resultset by rows and columns, just
//! assign query results directly to rust structures that fit the data
//! semantics. This approach allows, in contrast to many ORM mapping variants,
//! using the full flexibility of SQL (projection lists, all kinds of joins,
//! unions, etc, etc). Whatever query you need, you just use it, and whatever
//! result structure you need, you just use a corresponding rust structure into
//! which you deserialize the data.
//!
//! See
//! [code examples](code_examples/index.html)
//! for an overview.
//!
//! ## Disclaimer
//!
//! This driver is functionally operable and working well and fast.
//! However, its implementation still lacks some features:
//! some date/time/timestamp datatypes are missing, SSL is not yet supported.
//!
