在下面的代码中,如何将Interval::Minute
用作60
?
#[derive(Debug)]
enum Interval {
Minute = 60,
Hour = 3600,
Day = 86400,
}
fn main() {
let interval = 120;
let minute = Interval::Minute;
println!("Number of minutes: {:?}", interval/minute);
}
即,如何将其用作基础值的别名?
答案 0 :(得分:1)
您可以将其强制转换为整数类型:
let minute = Interval::Minute as i32;
另一种选择是在模块中使用const
,具体取决于您尝试执行的操作:
mod interval {
pub const MINUTE: i32 = 60;
}
fn main() {
let interval = 120;
let minute = interval::MINUTE;
println!("Number of minutes: {:?}", interval/minute);
}
