Module diesel::types

Types which represent a native SQL data type, and the conversions between them and Rust primitives. The structs in this module are only used as markers to represent a SQL type, and shouldn't be used in your structs. See the documentation for each type to see the Rust types that can be used with a corresponding SQL type. Additional types can be added by other crates.

To see which Rust types can be used with a given SQL type, see the "Implementors" section of the ToSql and FromSql traits, or see the documentation for that SQL type.

Any backend specific types are re-exported through this module

Modules

ops	Apps should not need to concern themselves with this module.

Structs

BigInt	The big integer SQL type.
Binary	The binary SQL type.
Bool	The boolean SQL type. On SQLite this is emulated with an integer.
Date	The date SQL type.
Double	The double precision float SQL type.
Float	The float SQL type.
Integer	The integer SQL type.
Interval	The interval SQL type.
Nullable	The nullable SQL type. This wraps another SQL type to indicate that it can be null. By default all values are assumed to be NOT NULL.
Numeric	The numeric SQL type.
SmallInt	The small integer SQL type.
Text	The text SQL type.
Time	The time SQL type.
Timestamp	The timestamp/datetime SQL type.

Enums

IsNull

Tiny enum to make the return type of ToSql more descriptive

Traits

Foldable
FromSql	How to deserialize a single field of a given type. The input will always be the binary representation, not the text.
FromSqlRow	How to deserialize multiple fields, with a known type. This type is implemented for tuples of various sizes.
HasSqlType
IntoNullable
NotNull
SqlOrd
ToSql	Serializes a single value to be sent to the database. The output will be included as a bind parameter, and is expected to be the binary format, not text.
