pub enum FunctionReturns {
None,
Scalar {
type_name: String,
},
SetOf {
type_name: String,
},
Table,
}Expand description
Declared result shape of a user-defined function.
Variants§
None
Procedures and functions whose result is shaped purely by
OUT parameters carry no explicit RETURNS clause.
Scalar
RETURNS <type> - includes RETURNS void and RETURNS record.
SetOf
RETURNS SETOF <type>.
Table
RETURNS TABLE (...). The column list lives in
CreateFunction::params as FunctionParamMode::Table
entries; this variant just records the set-returning shape.
