Module attrs 

Attribute markers for SQLiteTable derive macro.

These const markers are used within #[column(...)] and #[SQLiteTable(...)] attributes. Import them from the prelude to get IDE hover documentation.

Example

#[SQLiteTable(
    name = "users",
    strict,
    unique(columns(email, tenant_id)),
    check(name = "users_score_check", expr = "score >= 0")
)]
struct User {
    #[column(primary, autoincrement)]
    id: i32,
    #[column(unique)]
    email: String,
    tenant_id: i32,
    score: i32,
    metadata: String,
}

Structs

ColumnMarker

Marker struct for column constraint attributes.

NameMarker

Marker struct for the NAME attribute.

TableMarker

Marker struct for table-level attributes.

TypeMarker

Marker struct for column type attributes.

ViewMarker

Constants

ANY

Specifies an ANY column type (STRICT tables only).

BINARY collation: bytewise comparison of operands. The default for BLOB columns and any column without an explicit collation.

BLOB

Specifies a BLOB column type.

BOOLEAN

CASCADE

CASCADE action: Propagate the delete/update to referencing rows.

CHECK

COLLATE

Specifies a collation sequence for a text column.

DEFAULT

DEFAULT_SQL

Specifies a raw SQL default expression for new rows.

DEFINITION

Specifies a view definition SQL string or expression.

ENUM

Marks this column as storing an enum type.

EXISTING

Marks the view as existing (skip creation).

FOREIGN_KEY

INTEGER

Specifies an INTEGER column type.

JSON

Enables JSON serialization with TEXT storage.

JSONB

Enables JSON serialization with BLOB storage.

NAME

Specifies a custom name in the database.

NOCASE

NOCASE collation: ASCII case-insensitive comparison. Useful for text columns that need case-insensitive equality / sorting.

NO_ACTION

NO ACTION action: Similar to RESTRICT (default behavior).

NUMERIC

Specifies a NUMERIC column type.

ON_DELETE

Specifies the ON DELETE action for foreign key references.

ON_UPDATE

Specifies the ON UPDATE action for foreign key references.

PRIMARY

PRIMARY_KEY

Alias for PRIMARY.

REAL

Specifies a REAL column type.

REFERENCES

Establishes a foreign key reference to another table’s column.

RESTRICT

RESTRICT action: Prevent delete/update if referenced.

TEXT

Specifies a TEXT column type.

UNIQUE

WITHOUT_ROWID

Enables WITHOUT ROWID optimization for the table.

Type Aliases

ReferentialAction

Type alias for referential action markers (uses ColumnMarker for macro compatibility).
