Module 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§

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

Structs§

Arraypostgres_backend: The Array SQL type.
BigInt: The big integer SQL type.
Binary: The binary SQL type.
Bool: 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".
Citextpostgres_backend: The Citext SQL type. This is a PostgreSQL specific type.
Date: The date SQL type.
Datetimemysql_backend: Represents the MySQL datetime type.
Double: The double precision float SQL type.
Float: The float SQL type.
Inetpostgres_backend: The INET SQL type. This type can only be used with feature = "network-address" or feature = "ipnet-address".
Integer: The integer SQL type.
Interval: The interval SQL type.
Json: 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.
Nullable: The nullable SQL type.
Numeric: 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.
SmallInt: The small integer SQL type.
Text: The text SQL type.
Time: The time SQL type.
Timestamp: The timestamp SQL type.
Timestamptzpostgres_backend: The “timestamp with time zone” SQL type, which PostgreSQL abbreviates to timestamptz.
TimestamptzSqlitesqlite: The SQLite timestamp with time zone type
TinyInt: The tiny integer SQL type.
Unsignedmysql_backend: Represents the MySQL unsigned type.
Untyped: 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§

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