Trait RegisterWatch 

pub trait RegisterWatch: Send {
    // Required methods
    fn next<'life0, 'async_trait>(
        &'life0 mut self,
    ) -> Pin<Box<dyn Future<Output = BusResult<WatchEvent>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
    fn has_snapshot(&self) -> bool;
}

Required Methods

fn next<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = BusResult<WatchEvent>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn has_snapshot(&self) -> bool

True only after this watch delivered its snapshot on this connection.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
