AtomicCell

Struct AtomicCell 

Source
pub struct AtomicCell<T> { /* private fields */ }
Expand description

Атомарная ячейка с полностью безопасным API

§Безопасность

  • Конструктор гарантирует корректную инициализацию
  • Все операции с памятью инкапсулированы
  • Паника при невозможности создания (системная ошибка)

Implementations§

Source§

impl<T> AtomicCell<T>

Source

pub fn load(&self) -> T
where T: Copy,

Безопасно загрузить значение

§Safety

Этот метод безопасен, так как:

  • Вызывается только когда нет одновременной записи
  • Использует правильные гарантии памяти
Source

pub fn store(&self, value: T)

Безопасно сохранить значение

§Safety

Этот метод безопасен, так как:

  • Гарантируется уникальный доступ для записи
  • Нет одновременного чтения
Source

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

Получить указатель на данные (для совместимости)

Source

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

Source

pub fn try_new(value: T) -> Result<Self, AtomicCellError>

Создать новую атомарную ячейку с проверкой
