Struct SwmrCell 

pub struct SwmrCell<T: 'static> { /* private fields */ }

A single-writer, multi-reader cell with version-based garbage collection.

SwmrCell provides safe concurrent access where one writer can update the value and multiple readers can read it concurrently. Readers access the value by creating a LocalReader and pinning it.

单写多读单元，带有基于版本的垃圾回收。

SwmrCell 提供安全的并发访问，其中一个写入者可以更新值， 多个读者可以并发读取它。读者通过创建 LocalReader 并 pin 来访问值。

Implementations

impl<T: 'static> SwmrCell<T>

pub fn new(data: T) -> Self

Create a new SWMR cell with default settings and the given initial value.

使用默认设置和给定的初始值创建一个新的 SWMR 单元。

pub fn builder() -> SwmrCellBuilder<T>

Returns a builder for configuring the SWMR cell.

返回用于配置 SWMR 单元的构建器。

pub fn local(&self) -> LocalReader<T>

Create a new LocalReader for reading.

Each thread should create its own LocalReader and reuse it. LocalReader is !Sync and should not be shared between threads.

创建一个新的 LocalReader 用于读取。 每个线程应该创建自己的 LocalReader 并重复使用。 LocalReader 是 !Sync 的，不应在线程之间共享。

pub fn store(&mut self, data: T)

Store a new value, making it visible to readers. The old value is retired and will be garbage collected.

This operation increments the global version.

存储新值，使其对读者可见。 旧值已退休，将被垃圾回收。 此操作会增加全局版本。

pub fn collect(&mut self)

Manually trigger garbage collection. 手动触发垃圾回收。
