Struct core::nonzero::NonZero [] [src]

#[lang = "non_zero"]
pub struct NonZero<T: Zeroable>(_);
🔬 This is a nightly-only experimental API. (nonzero #27730)

needs an RFC to flesh out the design

A wrapper type for raw pointers and integers that will never be NULL or 0 that might allow certain optimizations.

Methods
