This library provides alternatives to the standard .unwrap* methods on Result and Option that don't require Debug to be implemented on the unexpected variant.


Please use cargo-edit to always add the latest version of this library:

cargo add debugless-unwrap


use assert_panic::assert_panic;
use debugless_unwrap::*;

#[derive(Copy, Clone)]
struct T;

let some = Some(T);
let none = Option::<T>::None;
let ok = Result::<T, T>::Ok(T);
let err = Result::<T, T>::Err(T);


assert_panic!({ err.debugless_unwrap(); });
assert_panic!({ ok.debugless_unwrap_err(); });

Code of Conduct



debugless-unwrap strictly follows Semantic Versioning 2.0.0 with the following exceptions:

  • The minor version will not reset to 0 on major version changes (except for v1).
    Consider it the global feature level.
  • The patch version will not reset to 0 on major or minor version changes (except for v0.1 and v1).
    Consider it the global patch level.

This includes the Rust version requirement specified above.
Earlier Rust versions may be compatible, but this can change with minor or patch releases.

Which versions are affected by features and patches can be determined from the respective headings in CHANGELOG.md.

No runtime deps
