Expand description
This library provides a convenient macro and function to track the location of error where it first happened.
§Examples
§Add dependency
track-error = { version = "0.1"}§How to use
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);
}
}
