Usage

Add track-error as a dependency

[dependencies]
track-error = "0.1"

Since this crate just provides a easy and friendly wrapper for the error.

For example:

use track_error::{Track, Tracked, track_error};

fn error_func() -> Result<(), String> {
    Err("something went wrong".to_string())
}

fn track_result() -> Result<(), Tracked<String>> {
    error_func().track()?;
    Ok(())
}

fn track_macro() -> Result<(), Tracked<String>> {
    let _ = error_func().map_err(|e| track_error!(e))?;
    Ok(())
}


fn main() {
    if let Err(e) = track_result() {
        println!("Error: {}", e);
        println!("Location: {}:{}", e.location().0, e.location().1);
    }
  
     if let Err(e) = track_macro() {
        println!("Error: {}", e);
        println!("Location: {}:{}", e.location().0, e.location().1);
    }
}
