Struct core::nonzero::NonZero [−][src]
#[lang = "non_zero"]pub struct NonZero<T: Zeroable>(_);
: use std::ptr::NonNull or std::num::NonZero* instead
🔬 This is a nightly-only experimental API. (nonzero #49137)
deprecated
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]
impl<T: Zeroable> NonZero<T>pub const unsafe fn new_unchecked(inner: T) -> Self[src]
pub const unsafe fn new_unchecked(inner: T) -> Self: use std::ptr::NonNull or std::num::NonZero* instead
🔬 This is a nightly-only experimental API. (nonzero #49137)
deprecated
Creates an instance of NonZero with the provided value. You must indeed ensure that the value is actually "non-zero".
pub fn new(inner: T) -> Option<Self>[src]
pub fn new(inner: T) -> Option<Self>: use std::ptr::NonNull or std::num::NonZero* instead
🔬 This is a nightly-only experimental API. (nonzero #49137)
deprecated
Creates an instance of NonZero with the provided value.
pub fn get(self) -> T[src]
pub fn get(self) -> T: use std::ptr::NonNull or std::num::NonZero* instead
🔬 This is a nightly-only experimental API. (nonzero #49137)
deprecated
Gets the inner value.
