添加依赖项

cargo add grange

或

grange = "0.1.*"

示例

use grange::*;

fn main() {
    for i in range!(1,2,=20){ // equal to (1..=20).step_by(2)
        println!("{}", i);
    }
    for i in range!(10,-1,=1){ // equal to (1..=10).rev() 
        println!("{}", i);
    }
    for i in range!(10,-2,=1){  // equal to (1..=10).step_by(2)
        println!("{}", i);
    }
    for i in range!(,3,10){ // equal to (0..10).step_by(3)
        println!("{}", i);
    }
    for i in range!("10..1"){  
        println!("{}", i);
    }
}
