pub extern "rust-intrinsic" fn add_with_overflow<T>(x: T, y: T) -> (T, bool)
🔬 This is a nightly-only experimental API. (
intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Performs checked integer addition.
The stabilized versions of this intrinsic are available on the integer
primitives via the
overflowing_add method. For example,
