[−][src]Function tract_nnef::internal::tract_downcast_rs::__std::intrinsics::variant_count
pub const 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
std::mem::variant_count
