Untry

Untry provides macros that do the “opposite” of the ? operator, in a way.

See the documentation for details.

lib.rs:

This is a collection of macros that work the “opposite” way of the ? operator. That is, they early-return if the input is successful, and evaluate to the error (if there is any).

This crate is no_std-compatible. There is a nightly-exclusive item guarded behing the nightly feature.
