Crate hdbconnect

Native rust database driver for SAP HANA(TM).

hdbconnect uses 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 for an overview.
