Struct CellWrapper

Source 
pub struct CellWrapper<T, K>
where
    T: 'static,
{ /* private fields */ }
Expand description

Safe cell header wrapper. If you create a CellWrapper with new_uninit, you should call ensure_init to handle

Implementations§

Source§

impl<T, K> CellWrapper<T, K>
where T: Cell + 'static,

Source

pub const unsafe fn _new_uninit(h: &'static T) -> Self

Source

pub const fn new_dummy(dummy_header: &'static T) -> Self

Source§

impl<T> CellWrapper<T, Forward>
where T: Cell + 'static,

Source

pub unsafe fn _new_init(h: &'static T) -> Option<Self>

Source

pub fn ensure_init(&self) -> Option<()>

If header wrapper was created with new_uninit, this function must be called to potentially initialize other cell’s memory.

Source

pub fn is_dummy(&self) -> bool

Source§

impl<T> CellWrapper<T, Backward>
where T: Cell + 'static,

Source

pub unsafe fn _new_init(h: &'static T) -> Option<Self>

Source

pub fn ensure_init(&self) -> Option<()>

If header wrapper was created with new_uninit, this function must be called to potentially initialize other cell’s memory.

Source

pub fn is_dummy(&self) -> bool
