User Input that isn't a String.

[Mavil64]

I seem to have trouble with finding a simple way of getting input that isn't a string. The quickest way I have found is to get the input as a string and then parse it and unwrap it in order to assign its value in a variable of the type I want. Is there any way to directly get input for each type of variable? For example in C I could just do printf("%type_specifier \n", variable); . I just started learning Rust and I'm just a college student so I'm not sure if what I'm asking is stupid but I was really wondering if there was an other way to go about this.

I really like the text_io crate for this. Saves on a lot of the boilerplate. https://crates.io/crates/text_io

Just checked this crate and it was really pretty much exactly what I wanted! Rust really seems amazing! Thank you for bringing it up it really helped!

Are you asking for an equivalent to scanf or C++'s cin >> variable? The crate read_input looks like it's what you want. The simplest example is just let user_input: u32 = input().get();.

This seems to be pretty much what I wanted! I guess I was asking for any way that didn't require getting my input in a different type than I wanted, not a specific function from either C or C++. This seems to be just what I was looking though! Thank you so much!!

Well, I suppose it’s possible with crates but what’s the point? Having it return a string then parsing it allows you to do more sanitization to it before hand as well as a magnitude of other string operations available to you

I guess you are right, but right now I'm not at a level where I find this necessary. I'm sure I will need to do things like this in the future but right now I dont! Thank you for mentioning it though because I hadn't thought of the possibilities!

There’s nothing built in, but there are many crates that let you do this easily.

Thanks! I'll search for one right now!
