Module types

Conversions between Rust and SQL types.

To see how each SQL type maps to a Rust type, see the corresponding types module for each database:

• Postgres: [postgres::types]
• MySQL: [mysql::types]
• SQLite: sqlite::types

Any external types that have had Type implemented for, are re-exported in this module for convenience as downstream users need to use a compatible version of the external crate to take advantage of the implementation.
