精细粒度

一个带有计圈功能和纳秒级分辨率的 Rust 计时器。

示例

获取单个测量值

extern crate fine_grained;

use fine_grained::Stopwatch;

fn main() {
    // Get a new stopwatch and start it.
    let mut stopwatch = Stopwatch::start_new();

    // Do something long and time it.
    // do_something_long();
    println!("Duration: {duration}ns", duration = stopwatch);
    stopwatch.stop();
}

获取重复任务的测量值和总时间

extern crate fine_grained;

use fine_grained::Stopwatch;

fn main() {
    // Get a new stopwatch and start it.
    let mut stopwatch = Stopwatch::start_new();

    // Do something repetitive you want to time.
    for _ in 0..10 {
        // do_something_repetitive();
        stopwatch.lap();
    }
    stopwatch.stop();

    // Print the timing results.
    for (i, &lap) in stopwatch.laps().into_iter().enumerate() {
        println!("Round {i}: {duration}ns", i = i, duration = lap);
    }
    println!("Total time: {duration}ns", duration = stopwatch);
}

获取多个独立任务的测量值和总时间

extern crate fine_grained;

use fine_grained::Stopwatch;

fn main() {
    // Get a new stopwatch and start it.
    let mut stopwatch = Stopwatch::start_new();

    // Do foo.
    // do_foo();
    let time_to_do_foo: u64 = stopwatch.lap();

    // Do bar.
    // do_bar();
    let time_to_do_bar: u64 = stopwatch.lap();

    // Do foobar.
    // do_foobar();
    let time_to_do_foobar: u64 = stopwatch.lap();

    stopwatch.stop();
    println!("Time to do foo: {duration}ns", duration = time_to_do_foo);
    println!("Time to do bar: {duration}ns", duration = time_to_do_bar);
    println!("Time to do foobar: {duration}ns", duration = time_to_do_foobar);
    println!("Total time: {duration}ns", duration = stopwatch);
}
