Struct sqlx_core::pool::CloseEvent

source · [−]

pub struct CloseEvent { /* private fields */ }

Expand description

A future that resolves when the pool is closed.

See Pool::close_event() for details.

Implementations

source

impl CloseEvent

source

pub async fn do_until<Fut: Future>(
&mut self,
fut: Fut
) -> Result<Fut::Output, Error>

Execute the given future until it returns or the pool is closed.

Cancels the future and returns Err(PoolClosed) if/when the pool is closed. If the pool was already closed, the future is never run.

Trait Implementations

source

impl FusedFuture for CloseEvent

source

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

source

impl Future for CloseEvent

type Output = ()

The type of value produced on completion.

source

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available. Read more
