Struct StoreColumn 

pub struct StoreColumn {
    pub name: String,
    pub col_type: StoreColumnType,
    pub primary_key: bool,
    pub auto_increment: bool,
    pub not_null: bool,
    pub unique: bool,
    pub default_value: String,
    pub identity: bool,
    pub indexed: bool,
    pub json_shape: Option<String>,
    pub line: u32,
    pub column: u32,
}

One column entry in an inline schema { col: Type [constraint…], … } block.

The closed-set constraint vocabulary is shared with the Python AST (StoreColumnNode): primary_key, auto_increment, not_null, unique, default <literal>.

Fields

name: String

col_type: StoreColumnType

primary_key: bool

auto_increment: bool

not_null: bool

unique: bool

default_value: String

Literal default value, source-text verbatim. The runtime does not interpolate; the database supplies the default. Empty when no default … constraint is declared.

identity: bool

v1.31.0 (D2) — true iff this column is declared with GENERATED ALWAYS AS IDENTITY or GENERATED BY DEFAULT AS IDENTITY in the live database (pg_attribute.attidentity is 'a' or 'd'). Distinct from auto_increment (which marks the legacy SERIAL pattern via a nextval(...) default expression). T803 treats an identity column as safe-to-omit from a persist because Postgres auto-fills it.

Backwards-compatibility (D5): the field defaults to false, matching v1.38.2 behavior for every column. A manifest written against v1.38.2 round-trips byte-identically.

indexed: bool

v2.26.0 (D1) — true iff the column is declared with the index constraint, e.g. payload: Json index. This is the program-visible declaration of an index as a CAPABILITY-HONEST EFFECT: the index is part of the source the deploy gate sees, never a silent out-of-band DBA action (doctrine: infrastructure is visible to the program). The index METHOD is chosen by the backend from the column type — a Json/Jsonb column gets a Postgres GIN path index (USING gin (col jsonb_path_ops)), any other column a plain b-tree. Defaults to false — a pre-v2.26.0 manifest round-trips byte-identically.

json_shape: Option<String>

v2.26.0 (D1) — the OPTIONAL shape LENS on a Json / Jsonb column: payload: Json<UserEvent> records Some("UserEvent"), a bare payload: Json records None. The lens is a COMPILE-TIME expectation only — the column’s physical type stays jsonb and the runtime navigates it totally regardless (a declared-but-absent field degrades to null, never crashes; doctrine open_data_is_total). The type-checker validates that the named shape is a declared struct type (axon-T840); the parser rejects a <T> on any non-Json column type (axon-T841). Only ever Some(_) for StoreColumnType::{Json, Jsonb}. Defaults to None — a v1.38–1.23 manifest round-trips byte-identically.
