Skip to main content Module sqlfunc Copy item path Source Modifiers 🔒 Modifiers passed as key-value pairs to the #[sqlfunc] macro. Arity 🔒 Arity classification for a function annotated with #[sqlfunc]. SqlName 🔒 A name for the SQL function. It can be either a literal or a macro, thus we
can’t use String or syn::Expr directly. arg_type 🔒 Determines the argument type of the nth argument of the function. binary_func 🔒 Produce a EagerBinaryFunc implementation. camel_case 🔒 determine_arity 🔒 Determines the arity of a function annotated with #[sqlfunc]. generate_test 🔒 is_nullable_type 🔒 Convert an identifier to a camel-cased identifier.
Checks if a parameter type accepts NULL. is_variadic_arg 🔒 Checks whether a parameter’s type is Variadic<...> or OptionalArg<...>,
which indicates the function should be treated as variadic regardless of
parameter count. is_variadic_type 🔒 Checks if a type is Variadic<T>. last_is_arena 🔒 Checks if the last parameter of the function is a &RowArena. non_nullable_position_checks 🔒 Generates per-position nullability checks for non-nullable parameters. output_type 🔒 Determine the output type for a function. Returns an error if the function
does not return a value. patch_lifetimes 🔒 Recursively patches lifetimes in a type, adding 'a to references without a lifetime
and recursing into generic arguments and tuples. sqlfunc Implementation for the #[sqlfunc] macro. The first parameter is the attribute
arguments, the second is the function body. The third parameter indicates
whether to include the test function in the output. unary_func 🔒 Produce a EagerUnaryFunc implementation. variadic_element_is_nullable 🔒 For a Variadic<T> type, checks if T accepts NULL. variadic_func 🔒 Produce an EagerVariadicFunc implementation.
