Expand description

A struct to manage receiving notifications for a asset

Implementations§

Source§

impl AssetUpdateObservation

Source

pub async fn recv_notification(&mut self) -> Option<(Asset, Option<AckToken>)>

Receives an updated Asset or None if there will be no more notifications when the unobservation is complete.

If there are notifications:

  • Returns Some(Asset, Option<AckToken>) on success
    • If auto ack is disabled, the AckToken should be used or dropped when you want the ack to occur. If auto ack is enabled, you may use (Asset, _) to ignore the AckToken.

A received notification can be acknowledged via the AckToken by calling AckToken::ack or dropping the AckToken.
