This crate provides tracked's procedural macro.

Please refer to the tracked crate for details.

tracked

A stringly-typed Error that includes #[track_caller] information.

Points you to the location in your code that errored, without the panic!.

Also lets you try an Option or a bool into a Result.

use tracked::tracked;

fn f() -> Option<()> {
    None
}

#[tracked]
fn main() -> Result<(), tracked::StringError> {
    true?;
    f()?;
    Ok(())
}
