What one row of duckdb_functions() says, before it is turned into values.

Fields

name: &'static str

The name as it is written in a query.

function_type: &'static str

scalar, aggregate or table, which are the three kinds rudb has.

alias_of: Option<&'static str>

The name this one resolves to, and None for a name that is its own.

return_type: Option<&'static str>

What the call produces, and None for a table function, whose columns are not one type.

parameters: Vec<String>

One name per argument, in order.

parameter_types: Vec<String>

One type per argument, in order, the same length as parameters.

varargs: Option<&'static str>

The type of the trailing variadic argument, for the names that take one.

has_side_effects: Option<bool>

Whether calling it twice can give two answers, and None for a table function, which is where upstream leaves this column null.

stability: Option<&'static str>

How much the engine may reuse a result, and None for a table function.
