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:

• PostgreSQL
• MySQL
• SQLite
• MSSQL

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.

Nullable

To represent nullable SQL types, Option<T> is supported where T implements Type. An Option<T> represents a potentially NULL value from SQL.

Re-exports

• pub use uuid;
• pub use uuid::Uuid;
• pub use rust_decimal::Decimal;

Modules

• chrono
• time

Structs

• 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.

Enums

• JsonValue
  Represents any valid JSON value.

Traits

• Type
  Indicates that a SQL type is supported for a database.
