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

C++ example:

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

In Rust I tried:

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

I could easily just declare a let i: i64 = var before the for loop
but I'd rather learn the correct way to doing this, but this resulted in

error: expected one of @ or in, found :
--> src/main.rs:2:10
|
2 | for i: i64 in 1..100 {
| ^ expected one of @ or in here


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);
}
