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.

Modules

bstr

chrono

ipnet

ipnetwork

mac_address

time

uuid

Generate and parse universally unique identifiers (UUIDs).

Structs

BStr

A wrapper for &[u8] that provides convenient string oriented trait impls.

BString

A wrapper for Vec<u8> that provides convenient string oriented trait impls.

BigDecimal

A big decimal type.

BitVec

The bitvector type.

Decimal

Decimal represents a 128 bit representation of a fixed-precision decimal number. The finite set of values of type Decimal are of the form m / 10^e, where m is an integer such that -2⁹⁶ < m < 2⁹⁶, and e is an integer between 0 and 28 inclusive.

Json

Json for json and jsonb fields

JsonRawValue

Reference to a range of bytes encompassing a single valid JSON value in the input data.

Text

Map a SQL text value to/from a Rust type using Display and FromStr.

Uuid

A Universally Unique Identifier (UUID).

Enums

JsonValue

Represents any valid JSON value.

Traits

Type

Indicates that a SQL type is supported for a database.
