Metadata information about a database column.

This structure is used internally to generate table schemas and map Rust types to SQL types. It is usually populated automatically by the #[derive(Model)] macro.

Fields

name: &'static str

The column name in the database.

sql_type: &'static str

The SQL type of the column (e.g., “TEXT”, “INTEGER”, “TIMESTAMPTZ”).

is_primary_key: bool

Whether this column is a Primary Key.

is_nullable: bool

Whether this column allows NULL values.

create_time: bool

Whether this column should be automatically populated with the creation timestamp.

update_time: bool

Whether this column should be automatically updated on modification (feature in progress).

unique: bool

Whether this column has a UNIQUE constraint.

index: bool

Whether an index should be created for this column.

foreign_table: Option<&'static str>

The name of the foreign table, if this is a Foreign Key.

foreign_key: Option<&'static str>

The name of the foreign column, if this is a Foreign Key.
