What can be done with Rust's generic FromStr object?

Question

Rust\'s str class has a parse method that returns a FromStr object. parse is templated, and so the type that\'s being parsed

Answer 1

It's just not clear what m is here, as there isn't enough information to say. Is it an i32? A u64? Nobody, including Rust, can know.

You need to do something to help figure out what type it is. Either pass it to a function expecting a specific type, or annotate it such that it can be determined what type it should be.
