Struct maybe_cell::unchecked::Maybe

#[repr(transparent)]pub struct Maybe<T> { /* fields omitted */ }

Equivalent to an UnsafeCell<MaybeUninit<T>>, this cell may hold uninitialized data.

Implementations

impl<T> Maybe<T>

pub const fn empty() -> Self

Create a new, empty Maybe<T>.

pub const fn new(data: T) -> Self

Create a new, populated Maybe<T>.

pub fn as_ptr(&self) -> *const T

Access the contained value as a constant pointer.

pub fn as_mut_ptr(&mut self) -> *mut T

Access the contained value as a mutable pointer.

pub unsafe fn as_ref(&self) -> &T

Obtain a reference to the contained value. This method is unsafe because the value may not have been initialized.

pub fn set_loaded(&self, _loaded: bool)

Override the loaded flag of the cell. This method is a no-op when using the unchecked implementation. It may be used when a value is inserted manually, for example by assigning to the dereferenced pointer.

pub fn clear(&self)

Drop the contained value in place.

pub fn load(&self) -> T

Load the contained value.

pub fn store(&self, value: T)

Store a new value in the cell.
