Struct WaitGuard 

Source 
pub struct WaitGuard { /* private fields */ }
Expand description

连接等待生命周期守卫；显式完成与取消只裁决一次。

Implementations§

Source§

impl WaitGuard

Source

pub fn finish(&mut self, outcome: AcquireOutcome)

业务作用：记录连接等待的唯一终态，日志不会改写连接结果。

参数说明：

  • outcome：必须在驱动错误类型被擦除前确定。

返回：无；重复完成不会重复计数。

impl Drop for WaitGuard

Source§

fn drop(&mut self)

业务作用：在 Future 取消或展开时回收在途计数并记录取消。

参数说明：无。

返回：无；已完成守卫不再产生样本。

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)
Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned. Read more
