Struct SharedFanoutLayoutCell 

pub struct SharedFanoutLayoutCell<const N: usize>(/* private fields */);

SharedFanoutLayout<N> wrapper that explicitly opts into interior mutability.

The v1 fanout layout is designed for concurrent mutation through atomics and raw pointers. Rust requires such mutation through a shared reference to be mediated by UnsafeCell.

This type is repr(transparent) over the ABI layout, so it can be used over the same mapped bytes as SharedFanoutLayout<N>.

Implementations

impl<const N: usize> SharedFanoutLayoutCell<N>

pub fn from_mut( shared: &mut SharedFanoutLayout<N>, ) -> &SharedFanoutLayoutCell<N>

Borrow a SharedFanoutLayoutCell view over a uniquely-mutable SharedFanoutLayout<N>.

pub unsafe fn from_ptr<'a>( ptr: *mut SharedFanoutLayout<N>, ) -> &'a SharedFanoutLayoutCell<N>

Borrow a SharedFanoutLayoutCell view over a raw pointer.

Safety

ptr must be valid for reads/writes for the lifetime 'a.
