Fields

name: String

data_type: String

High-level data type (e.g. “integer”, “character varying”)

udt_name: String

Underlying type name: udt_name (PG), column_type (MySQL), declared type (SQLite)

udt_schema: Option<String>

Schema in which udt_name is defined.

Populated by the Postgres backend (e.g. auth for an auth.role enum column, pg_catalog for builtins). None for MySQL/SQLite which have no per-type namespacing. Used to disambiguate enums/composites/domains when two schemas declare a type with the same name.

is_nullable: bool

is_primary_key: bool

ordinal_position: i32

schema_name: String

column_default: Option<String>

Raw column default expression (e.g. 'idle'::task_status)
