Expand description

A handle to communicate with the ExExManager.

Implementations§

Source§

impl ExExManagerHandle

Source

pub fn empty() -> Self

Creates an empty manager handle.

Use this if there is no manager present.

The handle will always be ready, and have a capacity of 0.

Source

pub fn send( &self, source: ExExNotificationSource, notification: ExExNotification, ) -> Result<(), SendError<(ExExNotificationSource, ExExNotification)>>

Synchronously send a notification over the channel to all execution extensions.

Senders should call Self::has_capacity first.

Source

pub async fn send_async( &mut self, source: ExExNotificationSource, notification: ExExNotification, ) -> Result<(), SendError<(ExExNotificationSource, ExExNotification)>>

Asynchronously send a notification over the channel to all execution extensions.

The returned future resolves when the notification has been delivered. If there is no capacity in the channel, the future will wait.

Source

pub fn capacity(&self) -> usize

Get the current capacity of the ExEx manager’s internal notification buffer.

Source

pub fn has_capacity(&self) -> bool

Whether there is capacity in the ExEx manager’s internal notification buffer.

If this returns false, the owner of the handle should NOT send new notifications over the channel until the manager is ready again, as this can lead to unbounded memory growth.

Source

pub const fn has_exexs(&self) -> bool

Returns true if there are ExEx’s installed in the node.

Source

pub fn finished_height(&self) -> Receiver<FinishedExExHeight>

The finished height of all ExEx’s.

Source

pub async fn ready(&mut self)

Wait until the manager is ready for new notifications.

Source

pub fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<()>

Wait until the manager is ready for new notifications.
