Is it possible to declare the type of the variable in Rust for loops?

Question

C++ example:

for (long i = 0; i < 101; i++) {
    //...
}

In Rust I tried:

for i: i64 in 1..100 {
    // ...
}
         


        

Answer 1

You can use an integer suffix on one of the literals you've used in the range. Type inference will do the rest:

for i in 1i64..101 {
    println!("{}", i);
}
