神器 flamer
flamer 是这样一个魔法东西,它可以方便地计算出你代码块的耗时。
基本方法,就是在你的代码/函数头和尾(自动)插入计时代码,最后汇总出一个耗时(报告)。用到了 nightly 的自定义属性,所以暂时只能以 nightly 版运行。看下例子:
extern crate flame;
use std::fs::File;
pub fn main() {
// Manual `start` and `end`
flame::start("read file");
let x = read_a_file();
flame::end("read file");
// Time the execution of a closure. (the result of the closure is returned)
let y = flame::span_of("database query", || query_database());
// Time the execution of a block by creating a guard.
let z = {
let _guard = flame::start_guard("cpu-heavy calculation");
cpu_heavy_operations_1();
// Notes can be used to annotate a particular instant in time.
flame::note("something interesting happened", None);
cpu_heavy_operations_2()
};
// Dump the report to disk
flame::dump_html(&mut File::create("flame-graph.html").unwrap()).unwrap();
// Or read and process the data yourself!
let spans = flame::spans();
println!("{} {} {}", x, y, z);
}
------------------------
extern crate flame;
#[macro_use] extern crate flamer;
#[flame]
// The item to apply `flame` to goes here.
