if you only limit yourself to the standard library, you would need to unwrap and rewrap the error - although admittedly since Result<T, E> is a type like any other, you could add an extension function (through a trait) so that you can add context more easily. If you use use one of the error handling libraries though, you're in luck - adding context is usually a single function call away: //without context some_function()?; //with context, using anyhow some_function().context("function returned error")?; //with wrap_err, using eyre some_function().wrap_err("function returned error eyre")?;
