Enum IrFreeExpr 

pub enum IrFreeExpr {
    Scalar(IrExpr),
    FreeObject(Vec<(String, IrExpr)>),
    NamedTupleRow(Vec<(String, IrExpr)>),
    Tuple(Vec<IrExpr>),
    AssertSet {
        fn_name: String,
        inner: Box<IrArraySource>,
        message: Option<IrExpr>,
    },
    CtePassthrough(String),
}

Variants

Scalar(IrExpr)

A single scalar value: SELECT {1}, SELECT 'hello', SELECT func().

FreeObject(Vec<(String, IrExpr)>)

A free object: SELECT { foo := 'bar', n := 42 }.

NamedTupleRow(Vec<(String, IrExpr)>)

A named tuple whose elements had to become a composite row rather than jsonb, because one of them holds an object – jsonb has no member kind for an object (see JsonMemberKind), so encoding it there would flatten it. Still a named tuple to the caller, not a free object.

Tuple(Vec<IrExpr>)

An anonymous tuple: SELECT (1, 'x').

AssertSet

A set-returning assert: SELECT ROW(v) FROM unnest(_pylon.fn(ARRAY(inner))) v. Used for assert_exists and assert_distinct which pass through the set.

Fields

fn_name: String

inner: Box<IrArraySource>

message: Option<IrExpr>

message := … — raised in place of the assert’s own text.

CtePassthrough(String)

Pass all rows from a scalar CTE through: SELECT "result" FROM "cte_name".
