Crate drizzle_types 

SQL type definitions shared by the drizzle crates.

• sql: compile-time SQL type markers’ capabilities (DataType, Compatible, Assignable, Numeric, Textual, …), also re-exported at the crate root.
• sqlite, postgres, mysql: each dialect’s type markers, column types and DDL definitions.
• Dialect: names a database.
• MigrationTracking, ConfigValue, Casing: migration settings.

Features

• std (default): standard library support.
• alloc: no_std with an allocator. Without std or alloc, only Dialect is available.
• serde, schemars: serialization and JSON Schema for the DDL types.
• uuid, chrono, geo-types, cidr, bit-vec: add the column types and Rust type mappings for those crates. time is accepted but currently adds nothing.
• col16, col32, col64, col128, col200: allow row-value tuples of up to that many columns (8 by default).
