How to get element of enum from String?

help
1

i want to try to get a element of enum from a string that given by user (runtime),just like: if i have string "A", and a enum A { A, B, C},then a function get "A" and return A::A.
i have tried macro and proc_macro_derive but in vain, i think the best solution that i hope is just use #[derive(something)] and give a parse_elem function,but i don't know how to do this, is it possible?

If applicable, I'd rely on serde. If not I'd just implement FromStr for the enum by hand.
