Module diesel::sql_types

Expand description

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.

Any backend specific types are re-exported through this module

Modules

Possible values for SqlType::IsNullable
Represents the output of numeric operators in SQL

Structs

Arraypostgres_backend
The Array SQL type.
The big integer SQL type.
The binary SQL type.
The boolean SQL type.
CCharpostgres_backend
The "char" SQL type. This is a PostgreSQL specific type. Used for e.g. setweight. Do not use in user tables.
Cidrpostgres_backend
The CIDR SQL type. This type can only be used with feature = "network-address" or feature = "ipnet-address".
The date SQL type.
Datetimemysql_backend
Represents the MySQL datetime type.
The double precision float SQL type.
The float SQL type.
Inetpostgres_backend
The INET SQL type. This type can only be used with feature = "network-address" or feature = "ipnet-address".
The integer SQL type.
The interval SQL type.
The JSON SQL type. This type can only be used with feature = "serde_json"
Jsonbpostgres_backend
The jsonb SQL type. This type can only be used with feature = "serde_json"
MacAddrpostgres_backend
The MACADDR SQL type.
Moneypostgres_backend
The PostgreSQL Money type.
The nullable SQL type.
The arbitrary precision numeric SQL type.
Oidpostgres_backend
The OID SQL type. This is a PostgreSQL specific type.
Rangepostgres_backend
The Range SQL type.
Recordpostgres_backend
The Record (a.k.a. tuple) SQL type.
The small integer SQL type.
The text SQL type.
The time SQL type.
The timestamp SQL type.
Timestamptzpostgres_backend
The “timestamp with time zone” SQL type, which PostgreSQL abbreviates to timestamptz.
The SQLite timestamp with time zone type
The tiny integer SQL type.
Unsignedmysql_backend
Represents the MySQL unsigned type.
Query nodes with this expression type do not have a statically at compile time known expression type.
Uuidpostgres_backend
The UUID SQL type. This type can only be used with feature = "uuid"

Traits

Are both values of IsNull are nullable?
A marker trait for accepting expressions of the type Bool and Nullable<Bool> in the same place
Represents SQL types which can be used with SUM and AVG
Indicates that a SQL type exists for a backend.
Converts a type which may or may not be nullable into its not nullable representation.
Converts a type which may or may not be nullable into its nullable representation.
A type level constructor for maybe nullable types
Is one value of IsNull nullable?
A marker trait indicating that a SQL type represents a single value, as opposed to a list of values.
Marker trait for types which can be used with MAX and MIN
A marker trait for SQL types
Information about how a backend stores metadata about given SQL types
