Function std::intrinsics::needs_drop

pub unsafe extern "rust-intrinsic" fn needs_drop<T>() -> bool
🔬 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 true if the actual type given as T requires drop glue; returns false if the actual type provided for T implements Copy.

If the actual type neither requires drop glue nor implements Copy, then may return true or false.
