Module sql_types

Types which represent a SQL data type.

The structs in this module are only used as markers to represent a SQL type. They should never be used in your structs. If you’d like to know the rust types which can be used for a given SQL type, see the documentation for that SQL type. Additional types may be provided by other crates.

To see which SQL type can be used with a given Rust type, see the “Implementors” section of FromSql.
