Fields

field_name: String

column_name: String

type_name: String

is_primary_key: bool

is_required: bool

is_foreign_key: bool

max_length: Option<usize>

is_auto_increment: bool

is_sequence: bool

Whether this column is backed by a database sequence (PostgreSQL).

sequence_name: Option<String>

The sequence name when is_sequence is true.

fk_referenced_table: Option<String>

Referenced table when is_foreign_key is true.

fk_referenced_column: Option<String>

Referenced column when is_foreign_key is true.

has_index: bool

Non-unique index on this column.

is_unique: bool

Unique constraint/index on this column.

fk_on_delete: Option<String>

ON DELETE clause for the FK constraint (e.g. “CASCADE”, “SET NULL”). None means no explicit clause (DB default applies).
