It appears that Rust does not to have labeled loops with break and continue by label the way Java has. Also, it appears that alt does not have fall-through the way switch in C has.
Are break and continue by label and/or fall-through in alt supported in some non-obvious and unadvertised way? If not, are there plans to add to these features? (While I understand that fall-through in switch is largely considered a misfeature, break and continue by label seem less controversial.) If there are no plans to add these features, what are the recommended ways to emulate these features in a way that compiles to efficient machine code? The use case I have is targeting Rust with the translator that currently targets C++ and generates the HTML parser in Gecko. (It uses goto hidden behind macros to emulate break and continue by label in C++.) -- Henri Sivonen hsivo...@iki.fi http://hsivonen.iki.fi/ _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
