Crate nanotime 

nanotime

A minimal, zero-dependency time utility crate for Rust CLI applications.

nanotime provides nanosecond-precision timestamps, human-readable formatting, relative time strings, and a simple elapsed-time stopwatch — all without pulling in heavy datetime libraries.

Quick start

use nanotime::{NanoTime, Elapsed};

// Current local time
let now = NanoTime::now();
println!("{}", now.datetime());  // "2026-02-23 14:30:05.042"

// From a Unix epoch
let t = NanoTime::from_epoch(1_000_000_000);
println!("{}", t.date());  // "2001-09-09"

// Relative time
let earlier = NanoTime::from_epoch(1_000_000_000);
let later   = NanoTime::from_epoch(1_000_003_600);
println!("{}", earlier.relative_to(&later));  // "1h ago"

// Stopwatch
let timer = Elapsed::start();
// ... do work ...
println!("took {}", timer);  // "42ms"

Structs

A simple stopwatch for measuring elapsed wall-clock time.
