hrtime

Human-Readable Time, stylized as hrtime, is a thin Rust library which converts seconds into either a colon-seperated time string and vice versa, or into the raw hour, minute, and second values.

Why?

Seemed like a simple library to make as I am learning Rust and thought it may prove useful to someone. As you can see by the versioning (0.2.0) it is currently in very early stages.

How?

From seconds

This crate only contains four functions, two "from" functions: from_sec and from_sec_padded, and two "to" functions: to_sec and to_time. The two "from" functions will convert a given u64 into a colon-separated time string, with from_sec_padded specifically introducing leading zeroes to reach the format "00:00:00" (HH:MM:SS). An example using from_sec:

let secs = 234;
println!("{secs} seconds is {}", hrtime::from_sec(secs));

Will print "123 seconds is 3:54",

and the same example but using from_sec_padded:

let secs = 234;
println!("{secs} seconds is {}", hrtime::from_sec_padded(secs));

Will print "234 seconds is 00:03:54"!

To seconds

The first "to" function is to_sec, which takes in a time string as an argument and attempts to convert it into the amount of seconds it represents. This string has some requirements to meet in order to work though, like having the values separated by colons (ex: "1:38" for a minute and 38 seconds) and there being no more than three colons (ex: "1:23:14:38" will panic). to_sec may be used like so:

let time = "10:50";
let secs = hrtime::to_sec(time);
println!("{time} is {secs} seconds");

Which prints "10:50 is 650 seconds"!

To time

The second "to" function is to_time, which returns the raw hour, minute, and second values represented by the given u64 respectively. This is returned as a tuple containing a u64 (hour), and two u8s (minute and seconds) more information can be seen in its documentation. to_time may be used like so:

let seconds = 650;
let (hrs, min, sec) = hrtime::to_time(seconds);
println!("{seconds} seconds is {hrs}h{min}m{sec}s");

Which prints "650 seconds is 0h10m50s"!
