Listening

Struct Listening 

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

Without a subscription it polls every interval and tries to subscribe again; a renewed subscription ends the wait at once, since a change made while nobody listened woke nobody.

Implementations§

Source§

impl Listening

Source

pub async fn start(db: Db, channel: Channel, interval: Duration) -> Self

Subscribes before returning, so a change committed after a read that follows is heard.

Source

pub async fn changed(&mut self)
