Struct SharedLayoutCell 

pub struct SharedLayoutCell(/* private fields */);

SharedLayout wrapper that explicitly opts into interior mutability.

The v1 events 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 SharedLayout.

Implementations

impl SharedLayoutCell

pub fn from_mut(shared: &mut SharedLayout) -> &SharedLayoutCell

Borrow a SharedLayoutCell view over a uniquely-mutable SharedLayout.

pub unsafe fn from_ptr<'a>(ptr: *mut SharedLayout) -> &'a SharedLayoutCell

Borrow a SharedLayoutCell view over a raw pointer.

Safety

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