Struct SQLFunctionResultLayout 

pub struct SQLFunctionResultLayout {
    pub kind: SQLFunctionResultKind,
    pub declared_type: ColumnType,
    pub source_record: Option<Vec<Option<ColumnType>>>,
    pub columns: Option<Vec<SQLFunctionResultColumn>>,
}

The SQL-owned result decision. A lone row value is distinct from a tuple whose individual columns need assignment coercion. Domains remain scalar, even when their base type is composite.

Fields

kind: SQLFunctionResultKind

declared_type: ColumnType

source_record: Option<Vec<Option<ColumnType>>>

Descriptor of a lone returned row, captured before the statement executes.

columns: Option<Vec<SQLFunctionResultColumn>>

Named composite attributes or OUT parameters; absent for scalar and unspecified record results.
