Does "ill-formed, no diagnostic required" exist in Rust?
⚓ Rust 📅 2026-04-19 👤 surdeus 👁️ 3Hello everyone!
The C++ standard defines certain programming mistakes (such as defining a function more than one time) to cause a program to be "ill-formed, no diagnostic required", which means if the program is compiled, it will have undefined behavior from the start of execution (not when non-compliant part is reached). I wonder, is there anything similar in Rust?
