This is a fork of [zeta12ti's `parse_duration`](https://github.com/zeta12ti/parse_duration).

Main differences:

* It fixes a DOS issue.
* It drops support for numbers bigger than ±9.22e18.
* It drops support for exponential notation.

This crate provides a function `parse` for parsing strings into durations.
The parser is based on the standard set by
[systemd.time](https://www.freedesktop.org/software/systemd/man/systemd.time.html#Parsing%20Time%20Spans),
but extends it significantly.
For example, negative numbers, decimals and exponents are allowed.

```
extern crate parse_duration;

use ::parse_duration0::parse;
use ::std::time::Duration;

// One hour less than a day
assert_eq!(parse("1 day -1 hour"), Ok(Duration::new(82_800, 0)));
// Extra things will be ignored
assert_eq!(
    parse("Duration: 1 hour, 15 minutes and 29 seconds"),
    Ok(Duration::new(4529, 0))
);
```
