Most of the finicky backtracking business can be implemented in declarative macros, which is very nice for code conciseness. In an experimental alternative framework I made such a macro that can so-far parse:
T
#[rest] T
#[rest] &str
Option<T>
(greedy)#[lazy] Option<T>
(lazy)Vec<T>
(greedy)
Where T: serenity::utils::Parse. All of these can be arranged arbitrarily.
It's used like this, which can relatively painlessly be generated by a procedural macro I think
let arg_string = "hello 1 2 3 foo bar";
let (hello, empty, numbers, foo_bar_member) = parse_args!(ctx, msg, arg_string =>
(&str),
#[lazy] (Option<&str>),
(Vec<u32>),
#[rest] (serenity::model::prelude::Member),
).await?
