What is the inverse of format! ?
I have a &str, and I want to see if it get be parsed as a Bool, as a i32, or an f32. I.e. I am looking for functions of type signature:
&str -> Option<bool> &str -> Option<i32> &str -> Option<f32>
It’s not hard to write these on my own, but I suspect there is a standard way to do these in rust.
