hhmmss

Format time and duration in chrono, std::time and time as HH:MM:SS or HH:MM:SS.xxx.

Why?

I just wanted to format chrono::Duration as HH:MM:SS in some of my crates. However there isn't a ready-to-use method for this. Format is only supported for instances. Neither time nor std::time's Duration support this. So I made this crate, mainly for my own convinience.

Usage

Add hhmmss to Cargo.toml:

toml [dependencies] hhmmss = "0.1"

Then:

```rust use hhmmss::Hhmmss;

fn main() { let stdduration = std::time::Duration::new(3661, 534000000); asserteq!(&stdduration.hhmmss(), "01:01:01"); asserteq!(&stdduration.hhmmssxxx(), "01:01:01.534"); let chronoduration = chrono::Duration::fromstd(stdduration).unwrap(); // needs chrono asserteq!(&chronoduration.hhmmss(), "01:01:01"); asserteq!(&chronoduration.hhmmssxxx(), "01:01:01.534"); let timeduration = time::Duration::fromstd(stdduration).unwrap(); // needs time asserteq!(&timeduration.hhmmss(), "01:01:01"); asserteq!(&time_duration.hhmmssxxx(), "01:01:01.534"); } ```
