Function std::intrinsics::size_of_val

pub unsafe extern "rust-intrinsic" fn size_of_val<T>(&T) -> usize where    T: ?Sized, 
🔬 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

The size of the referenced value in bytes.

The stabilized version of this intrinsic is std::mem::size_of_val.
