Crate arbitime 

Arbitime

A simple Rust library for timing code execution with convenient macros.

Features

• time! - Time code execution and return both duration and result
• format_time! - Time code execution and format duration as a string
• log_time! - Time code execution with automatic logging to stderr

Examples

Basic timing with time!

use arbitime::time;
 
let (duration, result) = time! {
    // Some expensive computation
    (1..=1000000).sum::<u64>()
};
 
println!("Result: {}, took: {:?}", result, duration);

Formatted timing with format_time!

use arbitime::format_time;
 
let (msg, result) = format_time!("Computing sum" => {
    (1..=1000).sum::<u32>()
});
 
println!("{}", msg); // "Computing sum - Execution time: ..."

Logging timing with log_time!

use arbitime::log_time;
 
// Single operation with custom message
let result = log_time!("Computing sum" => {
    (1..=1000).sum::<u32>()
});
 
// Simple timing without custom message
log_time! {
    (1..=100).sum::<u32>()
};

Macros

format_time

Times the execution of code blocks and formats the duration as a string.

log_time

Times the execution of code and automatically logs the duration to stderr.

time

Times the execution of a code block and returns both the duration and result.
