Hi! First post here. I like this community 😄 .
I'm still learning the basics of Rust. I'm learning std::io::stdin and I arrived here:
fn main() {
println!("Welcome to");
println!("Box simulator 1.0");
let mut response = String::new();
println!("Write the box number: \n(between 0 and 65 535)");
stdin().read_line(&mut response).expect("Failed input");
let tiny_box = match response
.trim_end() // remove the \r\n
.parse::<u16>()
{
Ok(number) => number,
Err(error) => match error.kind() {
IntErrorKind::PosOverflow => panic!("You can't pick a number greater than 65 535"),
IntErrorKind::NegOverflow => panic!("You can't pick a number less than 0"),
IntErrorKind::Empty => panic!("I read an empty value"),
other_error => {
panic!("Something wrong has happened: {:?}", other_error)
}
},
};
println!("you the number {:?}", tiny_box)
}
The objective is to make an app to ask if you would like to edit a box (add a string to the contents), print a box, or quit.
the match error.kind only matches number errors, but if I put a letter the compiler panics with:
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace```
Where can I catch the letter errors? (longer than 1 character, any other character other than `[epq]`
Thanks in advance!
