Receiver

Struct Receiver 

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

Receiver side of the channel 通道的接收端

Implementations§

Source§

impl<T> Receiver<T>

Source

pub fn recv(&mut self) -> RecvFuture<'_, T>

Receive a value from the channel 从通道接收值

Source

pub fn try_recv(&mut self) -> Result<T, RecvError>

Try to receive a value without blocking 尝试接收值而不阻塞

§Errors

Returns Err(RecvError::Closed) if the channel is empty and all senders are dropped. 如果通道为空且所有发送器已丢弃则返回 Err(RecvError::Closed)

Returns Err(RecvError::Empty) if the channel is empty but senders still exist. 如果通道为空但发送器仍然存在则返回 Err(RecvError::Empty)

§Panics

Panics if the internal mutex is poisoned (should never happen in normal operation). 如果内部互斥锁被污染则恐慌(正常操作中不应发生)。

Source

pub fn len(&self) -> usize

Get the number of messages in the channel buffer 获取通道缓冲区中的消息数量

§Panics

Panics if the internal mutex is poisoned (should never happen in normal operation). 如果内部互斥锁被污染则恐慌(正常操作中不应发生)。

Source

pub fn is_empty(&self) -> bool

Check if the channel is empty 检查通道是否为空
