Function core::intrinsics::abort

pub extern "rust-intrinsic" fn abort() -> !

🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Aborts the execution of the process.

Note that, unlike most intrinsics, this is safe to call; it does not require an unsafe block. Therefore, implementations must not require the user to uphold any safety invariants.

std::process::abort is to be preferred if possible, as its behavior is more user-friendly and more stable.

The current implementation of intrinsics::abort is to invoke an invalid instruction, on most platforms. On Unix, the process will probably terminate with a signal like SIGABRT, SIGILL, SIGTRAP, SIGSEGV or SIGBUS. The precise behaviour is not guaranteed and not stable.
