Function std::intrinsics::variant_count

pub extern "rust-intrinsic" fn variant_count<T>() -> usize

🔬 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

Returns the number of variants of the type T cast to a usize; if T has no variants, returns 0. Uninhabited variants will be counted.

The to-be-stabilized version of this intrinsic is variant_count.
