Struct Receiver 

pub struct Receiver { /* private fields */ }

One async callback for one signal of one model.

Usually produced by #[receiver(..)]; build one by hand with Receiver::new.

Implementations

impl Receiver

pub fn new<M, F>(name: SignalName, handler: F) -> Self

where M: Model, F: for<'a> Fn(&'a M, &'a SignalEvent<'a>) -> BoxFuture<'a, Result<(), SignalError>> + Send + Sync + 'static,

A receiver for signal name of model M.

handler gets the instance as &M; the downcast is checked, so a receiver never sees another model.

Receiver::new::<User, _>(SignalName::PostSave, |user, event| {
    Box::pin(async move { Ok(()) })
})

pub fn name(&self) -> SignalName

The signal this receiver listens to.

pub fn model(&self) -> &'static ModelMeta

Metadata of the model this receiver is typed on.
