print_each_line

它在执行过程中打印每一行和执行时间。它可以作为一个非常简单的性能分析器。

示例

use print_each_line::printline;
use dpss::dp;
use std::thread::sleep;
use std::time::{Duration};

#[printline]
fn main() {
    
    let arr = vec![-2445617,1415464,-1234475,-8719641,4811893];
    let result = dp::find_subset(arr, -3907748, 100);
    sleep(Duration::from_millis(1234));
    let route1: Vec<i32> = vec![-8719641, 4811893];
    let answer: Vec<Vec<i32>> = vec![route1];
    assert_eq!(result, answer);

}
