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

Expand description

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

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.

The stabilized versions of this intrinsic are available on the integer primitives via the `wrapping_mul` method. For example, `u32::wrapping_mul`
