Struct email::watch::config::WatchFn

pub struct WatchFn(Arc<dyn Fn(&Envelope) -> Pin<Box<dyn Future<Output = Result<()>> + Send>> + Send + Sync>);

Watch function.

This is just a wrapper around a function that takes a reference to an envelope.

Tuple Fields

0: Arc<dyn Fn(&Envelope) -> Pin<Box<dyn Future<Output = Result<()>> + Send>> + Send + Sync>

Implementations

impl WatchFn

pub fn new<F: Future<Output = Result<()>> + Send + 'static>( f: impl Fn(&Envelope) -> F + Send + Sync + 'static ) -> Self
