Function std::intrinsics::overflowing_add

pub unsafe extern "rust-intrinsic" fn overflowing_add<T>(a: T, b: T) -> T

Unstable (core_intrinsics)

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

Returns (a + b) mod 2^N, where N is the width of T in bits.
