1//! **SEE DOCUMENTATION BEFORE USE**. Generic database driver with the specific driver selected at runtime.
2//!
3//! The underlying database drivers are chosen at runtime from the list set via
4//! [`install_drivers`][self::driver::install_drivers]. Any use of `AnyConnection` or `AnyPool`
5//! without this will panic.
