# ODBC wrapper for safe idiomatic Rust

Library for writing [ODBC](https://msdn.microsoft.com/en-us/library/ms710154.aspx) applications in Rust.

If you're looking for raw ODBC FFI bindings check [odbc-safe](https://github.com/pacman82/odbc-safe) and [odbc-sys](https://github.com/pacman82/odbc-sys) crate.
