1//! `MySQL` types. The supported server baseline is MySQL 8.0.31.
2//!
3//! - [`types`]: zero-sized SQL type markers used for compile-time checks.
4//! - [`MySQLType`]: column types as written in DDL, including signedness and
5//!   inline `ENUM`/`SET` values.
6//! - [`TypeCategory`]: how a Rust field type maps to a `MySQL` column.
7//! - [`MySQLTypeCategory`]: families of SQL type declarations, used when parsing.
8//! - [`ddl`]: schema objects (tables, columns, indexes, ...) for migrations.
9//! - [`names`]: default constraint names that fit `MySQL` identifiers.
10//! - [`default`]: the canonical `DEFAULT` clause spelling shared by every
11//!   schema producer.
12//!
13//! PostgreSQL-only concepts such as arrays, `JSONB` and named enum types have
14//! no `MySQL` equivalent here.

22/// Zero-sized SQL type markers for the `MySQL` dialect.
23///
24/// Each marker stands for one SQL type at compile time, named after it
25/// (`IntUnsigned` is `INT UNSIGNED`, `Any` is untyped SQL such as a raw `SQL`
26/// fragment). Markers carry no length, precision or `ENUM` values; see
27/// [`MySQLType`] for those. The traits in [`crate::sql`] say which markers
28/// can be compared, assigned, or used in arithmetic.
