### Description This PR implements a backward-compatible way to define custom operators with fallible compute functions. The C++ API templated gained an optional `Fallible` argument. Closes #14287 ### Motivation and Context #14287 contains more context. The gist is that the current C-API defines compute operations of custom operators as functions returning `void` rather than an `OrtStatusPtr`. Currently, errors are often propagated across the C-ABI using C++ exceptions. That is very unsafe and undefined behavior. Moreover, it is difficult for languages other than C++ to use this approach even if they wanted to. A C-compliant sound and safe way to propagate errors allows for non-C++ fallible custom operators. ### An example in action https://github.com/cbourjau/ort-custom-op/pull/6/files is a demonstration of how this PR can be used to write safe and fallible custom operators in Rust. |
