odbc-sys 0.8.2

//! ODBC types those representation is compatible with the ODBC C API.
//!
//! This layer has not been created using automatic code generation. It is incomplete, i.e. it does
//! not contain every symbol or constant defined in the ODBC C headers. Symbols which are
//! deprecated since ODBC 3 have been left out intentionally. While some extra type safety has been
//! added by grouping some of C's `#define` constants into `enum`-types it mostly offers the same
//! power (all) and safety guarantess(none) as the wrapped C-API.
//! ODBC 4.0 is still under development by Microsoft, so these symbols are deactivated by default
//! in the cargo.toml
