Struct core::nonzero::NonZero
[−]
[src]
pub struct NonZero<T: Zeroable>(_);
A wrapper type for raw pointers and integers that will never be NULL or 0 that might allow certain optimizations.
Methods
impl<T: Zeroable> NonZero<T>[src]
const unsafe fn new(inner: T) -> NonZero<T>
Creates an instance of NonZero with the provided value. You must indeed ensure that the value is actually "non-zero".
Trait Implementations
impl<T: Zeroable> Deref for NonZero<T>[src]
type Target = T
The resulting type after dereferencing
fn deref(&self) -> &T
The method called to dereference a value
impl<T: Zeroable + CoerceUnsized<U>, U: Zeroable> CoerceUnsized<NonZero<U>> for NonZero<T>[src]
Derived Implementations
impl<T: Hash + Zeroable> Hash for NonZero<T>[src]
fn hash<__HT: Hasher>(&self, __arg_0: &mut __HT)
Feeds this value into the state given, updating the hasher as necessary.
fn hash_slice<H: Hasher>(data: &[Self], state: &mut H) where Self: Sized1.3.0
Feeds a slice of this type into the state provided.
