🕒 nano-clock

Ultra-fast date/time formatting for HTTP headers and system profiling.
Written in Rust, sprinkled with inline assembly, optimized for the lowest latency possible.

---

🔥 Features

• Returns current date/time in (i32, u8, u8, u8, u8, u8, u8) tuple format
  (year, month, day, hour, minute, second, weekday)
• Blazing-fast formatting of HTTP date headers (Date: ... GMT) in preallocated buffers
• Optional inline assembly (nano_clock_asm) for even lower latency
• Includes both time() (wall-clock) and clock_gettime(CLOCK_MONOTONIC) for monotonic measurements
• Zero allocations, no String, no chrono, no nonsense.

📦 Example

use nano_clock::{nano_clock, nano_http_date};

fn main() {
    let (y, m, d, h, min, s, w) = nano_clock();
    println!("Now: {y:04}-{m:02}-{d:02} {h:02}:{min:02}:{s:02} (weekday: {w})");

    let mut buf = [0u8; 35];
    unsafe {
        nano_http_date(&mut buf, false);
    }
    println!("{}", std::str::from_utf8(&buf).unwrap());
}
