Function creusot_contracts::std::intrinsics::variant_count

pub const fn variant_count<T>() -> usize

🔬This is a nightly-only experimental API. (core_intrinsics)

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.

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 to-be-stabilized version of this intrinsic is crate::mem::variant_count.
