Execution Time

This Rust project provides a simple way to measure and display the execution time of code blocks. It allows you to start a timer and then print the elapsed time in a human-readable format, including days, hours, minutes, and seconds.

Usage

1. Add the dependency to your Cargo.toml file:

   [dependencies]
   execution-time = "0.1"
   

2. Import and Use the library in your main.rs file.

   use execution_time::ExecutionTime;
   
   fn main() {
       let timer = ExecutionTime::start();
   
       // Simulate some work being done
       std::thread::sleep(std::time::Duration::from_millis(1234));
   
       // Print the elapsed time
       timer.print_elapsed_time();
       // or 
       // println!("Elapsed time: {}", timer.get_elapsed_time());
   }
   

3. Examples

   To run the examples and see the output for different elapsed times:

   1. Clone the repository and run the tests:

   git clone https://github.com/claudiofsr/execution-time.git
   cd execution-time
   cargo test -- --show-output
   

   2. The output:

   ---- tests::elapsed_time_less_than_minute stdout ----
   total_seconds: 0.01516345
   formatted_output: 0.0152 second
   
   ---- tests::elapsed_time_more_than_minute stdout ----
   total_seconds: 65.080012345
   formatted_output: 1 minute, 5.0800 seconds (65.0800 seconds)
   
   ---- tests::elapsed_time_more_than_hour stdout ----
   total_seconds: 3700.05689123
   formatted_output: 1 hour, 1 minute, 40.0569 seconds (3700.0569 seconds)
   
   ---- tests::elapsed_time_more_than_day stdout ----
   total_seconds: 86400.0 + 2.0 * 3600.0 + 5.0 * 60.0 + 28.03
   formatted_output: 1 day, 2 hours, 5 minutes, 28.0300 seconds (93928.0300 seconds)
