go没有的，rust有呢~~
fn largest<T: PartialOrd + Copy>(list: &[T]) -> T { let mut largest = list[0]; for &item in list.iter() { if item > largest { largest = item; } } largest } fn main() { let number_list = vec![34, 56, 78, 34, 677]; let result = largest(&number_list); println!("The largest number is {}", result); let char_list = vec!['r', 'a', 'v', 'm', 'd']; let result = largest(&char_list); println!("The largest char is {}", result); }转载于:https://www.cnblogs.com/aguncn/p/11406946.html
