Human readable elapsed time string
Overview
This is a library for human readable elapsed time string
Prerequisites
Rust 1.58 or newer
Usage
Put this in your Cargo.toml
:
[dependencies]
human-time="0"
Examples
Convert a duration to a human readable string
use std::{
thread,
time::{Duration, Instant},
};
use human_time::ToHumanTimeString;
fn main() {
let start = Instant::now();
thread::sleep(Duration::from_secs(1));
let costs: Duration = start.elapsed();
println!("costs {}", costs.to_human_time_string());
println!(
"costs {}",
Duration::from_secs(88401 * 2 * 8).to_human_time_string()
);
println!(
"costs {}",
Duration::from_millis(8840003).to_human_time_string()
);
}
Output
costs 1s,202μs
costs 16d,8h,53m,36s
costs 2h,27m,20s,3ms
Convert a duration to a human readable string with format.
use std::time::Duration;
use human_time::ToHumanTimeString;
fn main() {
println!(
"costs {}",
Duration::from_millis(8840003).to_human_time_string_with_format(
|n, unit| {
format!(
"{n}{}",
match unit {
"d" => "days".to_owned(),
"h" => "hours".to_owned(),
"m" => "minutes".to_owned(),
"s" => "seconds".to_owned(),
"ms" => "ms".to_owned(),
other => other.to_string(),
}
)
},
|acc, item| format!("{} {}", acc, item)
)
);
}
Output
costs 2hours 27minutes 20seconds 3ms
Print function time-consuming with elapsed macro
use std::{fmt::Display, thread, time::Duration};
fn main() {
foo(1);
}
//use log::debug;
//#[human_time::elapsed(output = "debug")]
//#[human_time::elapsed(output = "eprintln")]
// #[human_time::elapsed(output = "println")] //default
#[human_time::elapsed()]
fn foo<T>(_x: T)
where
T: Display,
{
thread::sleep(Duration::from_millis(1000));
}
#[human_time::elapsed(output = "eprintln")]
async fn bar() {
thread::sleep(Duration::from_millis(1000));
}
Output
fn foo costs 1s,2ms,837μs
