🔬This is a nightly-only experimental API. (

)Expand description
Performs checked integer multiplication
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 overflowing_mul
method. For example,
u32::overflowing_mul
