One introspected column.

Fields

name: String

ty: SqlType

primary_key: bool

nullable: bool

fk_target: Option<String>

The referenced table when this column is a foreign key, else None. Drives rendering the field as ForeignKey<Target> rather than a bare integer, and populates Column::fk_target in the initial migration.

unique: bool

A single-column UNIQUE constraint / unique index covers this column.

index: bool

A single-column (non-unique) index covers this column — rendered as #[umbral(index)].

default: Option<String>

The recovered constant DB default ('active', 0, true), cleaned of Postgres ::type casts and surrounding quotes. None when the column has no default, or one umbral can’t represent as a #[umbral(default)] literal — a sequence (nextval(...)) or function call. A CURRENT_TIMESTAMP / now() default on a temporal column is lifted to auto_now_add instead of landing here.

auto_now_add: bool

The column is populated with the current time on INSERT — recovered from a CURRENT_TIMESTAMP / now() default on a temporal column, or (under --framework django) a created*-named timestamp. Renders #[umbral(auto_now_add)].

auto_now: bool

The column is refreshed to the current time on every write. Not expressible as DB metadata on Postgres/SQLite (Django sets it in Python), so recovered only by the --framework django name heuristic (updated* / modified*). Renders #[umbral(auto_now)].

choices: Vec<String>

The closed set of values a native DB enum column accepts, in enumsortorder. Non-empty only for a Postgres USER-DEFINED enum column: the type stays SqlType::Text and the field renders as the generated [Choices] enum named by Self::enum_type, carrying a #[umbral(choices)] attribute (which the migration lowers to a CHECK (col IN (...)) constraint). Empty for every non-enum column — SQLite has no native enum type, so its path never populates this.

enum_type: Option<String>

The Postgres enum type name backing a choices column (PaymentMethod), or None when the column isn’t a native enum. Drives the generated Rust enum’s name and lets columns sharing one DB enum type reuse a single generated enum rather than each emitting its own.
