Trait multiversx_sc_snippets::imports::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>(loader: L, arg_names: Self::ArgNames) -> Self
       where L: TopDecodeMultiInput;
}

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.
