Trait ArgNestedTuple

pub trait ArgNestedTuple<AA>
where
    AA: EndpointArgumentApi + ManagedTypeApi + ErrorApi,
{
    type ArgNames;

    // Required methods
    fn check_num_single_args(index: i32);
    fn next_single_arg(index: i32, arg_names: Self::ArgNames) -> Self;
    fn next_multi_arg<L: TopDecodeMultiInput>(
        loader: L,
        arg_names: Self::ArgNames,
    ) -> Self;
}

Models an argument tree of the form (arg1, (arg2, ... (argn, ()))), used for retrieving endpoint arguments.

It translates to a small algorithm determined at compile-time. That is why all methods are inlined.

Required Methods

fn check_num_single_args(index: i32)

fn next_single_arg(index: i32, arg_names: Self::ArgNames) -> Self

fn next_multi_arg<L: TopDecodeMultiInput>( loader: L, arg_names: Self::ArgNames, ) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
