Crate hdbconnect

Experimental native rust database driver for SAP HANA(TM).

Works with SAP HANA 1 and SAP HANA 2.

hdbconnect uses serde (via serde_db) to simplify the data exchange between your code and the driver, both for input parameters to prepared statements and for results that you get from the database. There is no need to iterate over a resultset by rows and columns!

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.

Although being functionally operable and working well and fast, this driver is still in an incomplete state: some datatypes are missing, SSL is not yet supported.

Modules

code_examples	Here are some code examples for the usage of this database driver.
metadata	Types for describing metadata.
types	Types that are used within the content part of a ResultSet.

Structs

ConnectParams	An immutable struct with all information necessary to open a new connection to a HANA database.
ConnectParamsBuilder	A builder for ConnectParams.
Connection	Connection object.
ConnectionManager
PreparedStatement	Allows injection-safe SQL execution and repeated calls with different parameters with as few roundtrips as possible.
ResultSet	Contains the result of a database read command, including the describing metadata.
Row	A generic implementation of a single line of a ResultSet.

Enums

HdbError	Represents all possible errors that can occur in hdbconnect.
HdbResponse	Represents all possible non-error responses to a database command.
HdbReturnValue	An enum that describes a single database return value.
HdbValue	Enum for all supported database value types.

Traits

IntoConnectParams

A trait implemented by types that can be converted into a ConnectParams.
