Trait Pinger 

Source 
pub trait Pinger: Send + Sync {
    // Required method
    fn ping<'life0, 'async_trait>(
        &'life0 self,
    ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}
Expand description

Trait every protocol implementation provides. async fn is wrapped by async-trait so the trait stays object-safe — knockknock dispatches via Box<dyn Pinger> and that requires dyn-safety.

Required Methods§

Source

fn ping<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility§

This trait is dyn compatible.

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