Module odbc_api::handles

Provides basic abstraction over valid (i.e. allocated ODBC handles).

Two decisions are already baked into this module:

• Treat warnings by logging them with log.
• Use the Unicode (wide) variants of the ODBC API.

Structs

ColumnDescription	Describes the type and attributes of a column.
Connection	The connection handle references storage of all information about the connection to the data source, including status, transaction state, and error information.
Environment	An Environment is a global context, in which to access data.
ParameterDescription	Description of a parameter associated with a parameter marker in a prepared statement. Returned by crate::Prepared::describe_param.
Record	ODBC Diagnostic Record
StatementImpl	Wraps a valid (i.e. successfully allocated) ODBC statement handle.

Enums

DataType	Enumeration over valid SQL Data Types supported by ODBC
Error	Error type used to indicate a low level ODBC call returned with SQL_ERROR.
Nullability	Indication of whether a column is nullable or not.

Traits

AsHandle	Provides access to the raw underlying ODBC handle.
CData	Provides description of C type layout and pointers to it. Used to bind and buffers to ODBC statements.
CDataMut	A type which can be bound mutably to ODBC.
HasDataType	Can be bound to a single placeholder in an SQL statement.
Statement	An ODBC statement handle. In this crate it is implemented by self::StatementImpl. In ODBC Statements are used to execute statements and retrieve results. Both parameter and result buffers are bound to the statement and dereferenced during statement execution and fetching results.
