Enum FunctionParamMode 

pub enum FunctionParamMode {
    In,
    Out,
    InOut,
    Table,
}

Parameter mode of a CREATE FUNCTION / CREATE PROCEDURE argument. Mirrors PostgreSQL’s FunctionParameterMode.

Variants

In

IN (also the default when no mode is written).

Out

OUT - shapes the result row, not part of a function’s call signature (but part of a procedure’s).

InOut

INOUT - accepted as input and returned in the result row.

Table

RETURNS TABLE (col type, ...) column. Behaves like an OUT parameter of a set-returning function.
