Implementations§

Source§

impl PubSubHub

Source

pub fn new(storage_path: PathBuf) -> Self

Source

pub fn publish<S>(&self, new_value: S)
where S: Into<String>,

Publishes new_value.

  • All pending futures are woken.
  • Later calls to watch_for_change() will be evaluated against new_value.
Source

pub fn watch_for_change<S>(&self, last_value: Option<S>) -> PubSubFuture<'_> ⓘ
where S: Into<String>,

Watches the value stored in this hub, resolving when the stored value differs from last_value.

Source

pub fn get_value(&self) -> Option<String>
