1//! Attribute markers for PostgresTable derive macro.
2//!
3//! These const markers are used within `#[column(...)]` and `#[PostgresTable(...)]`
4//! attributes. Import them from the prelude to get IDE hover documentation.
5//!
6//! # Example
7//! ```ignore
8//! # use drizzle::postgres::prelude::*;
9//!
10//! #[PostgresTable(NAME = "users")]
11//! struct User {
12//!     #[column(PRIMARY, SERIAL)]
13//!     id: i32,
14//!     #[column(UNIQUE)]
15//!     email: String,
16//!     metadata: String,
17//! }
18//! ```

20/// Marker struct for column constraint attributes.

24//------------------------------------------------------------------------------
25// Primary Key Constraints
26//------------------------------------------------------------------------------
27
28/// Marks this column as the PRIMARY KEY.
29///
30/// ## Example
31/// ```ignore
32/// #[column(PRIMARY)]
33/// id: i32,
34/// ```
35///
36/// See: <https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-PRIMARY-KEYS>
37pub const PRIMARY: ColumnMarker = ColumnMarker;
38
39/// Alias for [`PRIMARY`].
40pub const PRIMARY_KEY: ColumnMarker = ColumnMarker;
41
42//------------------------------------------------------------------------------
43// Auto-increment Types
44//------------------------------------------------------------------------------
45
46/// Creates a SERIAL column (auto-incrementing 32-bit integer).
47///
48/// ## Example
49/// ```ignore
50/// #[column(PRIMARY, SERIAL)]
51/// id: i32,
52/// ```
53///
54/// See: <https://www.postgresql.org/docs/current/datatype-numeric.html#DATATYPE-SERIAL>
55pub const SERIAL: ColumnMarker = ColumnMarker;
56
57/// Creates a BIGSERIAL column (auto-incrementing 64-bit integer).
58///
59/// ## Example
60/// ```ignore
61/// #[column(PRIMARY, BIGSERIAL)]
62/// id: i64,
63/// ```
64///
65/// See: <https://www.postgresql.org/docs/current/datatype-numeric.html#DATATYPE-SERIAL>
66pub const BIGSERIAL: ColumnMarker = ColumnMarker;
67
68/// Creates a SMALLSERIAL column (auto-incrementing 16-bit integer).
69///
70/// ## Example
71/// ```ignore
72/// #[column(PRIMARY, SMALLSERIAL)]
73/// id: i16,
74/// ```
75///

78
79//------------------------------------------------------------------------------
80// Uniqueness Constraints
81//------------------------------------------------------------------------------
82
83/// Adds a UNIQUE constraint to this column.
84///
85/// ## Example
86/// ```ignore
87/// #[column(UNIQUE)]
88/// email: String,
89/// ```
90///
91/// See: <https://www.postgresql.org/docs/current/ddl-constraints.html#DDL-CONSTRAINTS-UNIQUE-CONSTRAINTS>
92pub const UNIQUE: ColumnMarker = ColumnMarker;
93
94//------------------------------------------------------------------------------
95// Identity Columns
96//------------------------------------------------------------------------------
97
98/// Creates a GENERATED IDENTITY column with configurable mode.
99///
100/// ## Syntax
101/// - `identity(always)` - User values rejected unless OVERRIDING SYSTEM VALUE
102/// - `identity(by_default)` - User values take precedence
103///
104/// ## Example
105/// ```ignore
106/// // GENERATED ALWAYS AS IDENTITY - strictest mode
107/// #[column(identity(always), primary)]
108/// id: i64,
109///
110/// // GENERATED BY DEFAULT AS IDENTITY - allows override
111/// #[column(identity(by_default), primary)]
112/// id: i64,
113/// ```
114///
115/// ## Technical Details
116/// PostgreSQL's identity columns are SQL-standard compliant, unlike SERIAL.
117/// Use ALWAYS for auto-generated IDs, BY DEFAULT when you need to occasionally set values.
118///
119/// See: <https://www.postgresql.org/docs/current/ddl-identity-columns.html>
120pub const IDENTITY: ColumnMarker = ColumnMarker;
121
122/// Marks a column as a GENERATED AS (expression) column.
123///
124/// ## Syntax
125/// - `generated(stored, "expression")` - Computed on write, stored on disk
126/// - `generated(virtual, "expression")` - Computed on read, not stored (PostgreSQL 17+)
127///
128/// ## Example
129/// ```ignore
130/// #[column(generated(stored, "price * quantity"))]
131/// total: i32,
132///
133/// #[column(generated(virtual, "first_name || ' ' || last_name"))]
134/// full_name: String,
135/// ```
136///
137/// ## Technical Details
138/// Generated columns cannot be written to directly.
139/// STORED columns are computed and stored on write.
140/// VIRTUAL columns are computed on read (PostgreSQL 17+).
141///
142/// See: <https://www.postgresql.org/docs/current/ddl-generated-columns.html>
143pub const GENERATED: ColumnMarker = ColumnMarker;

145//------------------------------------------------------------------------------
146// Serialization Modes
147//------------------------------------------------------------------------------
148
149/// Enables JSON serialization with JSON type storage.
150///
151/// ## Example
152/// ```ignore
153/// #[column(JSON)]
154/// metadata: UserMetadata,
155/// ```
156///
157/// Requires the `serde` feature. The field type must implement `Serialize` and `Deserialize`.
158///
159/// See: <https://www.postgresql.org/docs/current/datatype-json.html>
160pub const JSON: ColumnMarker = ColumnMarker;
161
162/// Enables JSON serialization with JSONB storage.
163///
164/// ## Example
165/// ```ignore
166/// #[column(JSONB)]
167/// config: AppConfig,
168/// ```
169///
170/// JSONB is the recommended JSON storage format for most use cases.
171/// It supports indexing and efficient querying.
172///
173/// Requires the `serde` feature. The field type must implement `Serialize` and `Deserialize`.
174///
175/// See: <https://www.postgresql.org/docs/current/datatype-json.html>
176pub const JSONB: ColumnMarker = ColumnMarker;
177
178/// Marks this column as storing an enum type.
179///
180/// ## Example
181/// ```ignore
182/// #[column(ENUM)]
183/// role: Role,
184/// ```
185///
186/// For PostgreSQL native ENUM types or text-based enum storage.

192// Default Value Parameters
193//------------------------------------------------------------------------------
194
195/// Specifies a function to generate default values at runtime.
196///
197/// The function is called for each insert when no value is provided.
198///
199/// ## Example
200/// ```ignore
201/// #[column(DEFAULT_FN = Uuid::new_v4)]
202/// id: Uuid,
203/// ```
204///
205/// ## Difference from DEFAULT
206/// - `DEFAULT_FN`: Calls the function at runtime for each insert (e.g., UUID generation)
207/// - `DEFAULT`: Uses a fixed compile-time value
208pub const DEFAULT_FN: ColumnMarker = ColumnMarker;
209
210/// Specifies a fixed default value for new rows.
211///
212/// ## Example
213/// ```ignore
214/// #[column(DEFAULT = 0)]
215/// count: i32,
216///
217/// #[column(DEFAULT = "guest")]
218/// role: String,
219/// ```
220///
221/// For runtime-generated values (UUIDs, timestamps), use [`DEFAULT_FN`] instead.
222///
223/// See: <https://www.postgresql.org/docs/current/ddl-default.html>
224pub const DEFAULT: ColumnMarker = ColumnMarker;
225
226/// Establishes a foreign key reference to another table's column.

239/// ## Example

241/// #[column(REFERENCES = User::id, ON_DELETE = CASCADE)]
242/// user_id: i32,
243/// ```
244///
245/// ## Supported Actions
246/// - `CASCADE`: Delete rows that reference the deleted row
247/// - `SET_NULL`: Set the column to NULL when referenced row is deleted
248/// - `SET_DEFAULT`: Set the column to its default value
249/// - `RESTRICT`: Prevent deletion if referenced
250/// - `NO_ACTION`: Similar to RESTRICT (default)
