Struct feattle::BackgroundSync [−][src]
pub struct BackgroundSync<F> { /* fields omitted */ }
Expand description
Spawn a tokio task to poll Feattles::reload()
continuously
A feattles instance will only ask the persistence layer for the current values when the
Feattles::reload()
method is called. This type would do so regularly for you, until the
Feattles
instance is dropped.
Example
use feattle_core::{feattles, Feattles};
use feattle_sync::BackgroundSync;
use feattle_core::persist::NoPersistence;
use std::sync::Arc;
feattles! {
struct MyToggles {
a: bool,
}
}
// `NoPersistence` here is just a mock for the sake of the example
let toggles = Arc::new(MyToggles::new(NoPersistence));
BackgroundSync::new(&toggles).spawn();
Implementations
Create a new poller for the given feattles instance. It will call Arc::downgrade()
to
detect when the value is dropped.
Set both Self::ok_interval
and Self::err_interval
After a successful reload, will wait for this long before starting the next one. By default this is 30 seconds.
After a failed reload, will wait for this long before starting the next one. By default this is 60 seconds.
Spawn a new tokio task, returning its handle. Usually you do not want to anything with the returned handle, since the task will run by itself until the feattles instance gets dropped.
Operational logs are generated with the crate [log
].
