Trait Handler 

pub trait Handler:
    Send
    + Sync
    + 'static {
    // Required method
    fn handle<'life0, 'async_trait>(
        &'life0 self,
        ctx: Context,
    ) -> Pin<Box<dyn Future<Output = BotResult<()>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

Core trait for all update handlers.

Implementors receive a Context and return a future resolving to BotResult<()>.

The return value does not influence routing. The dispatcher runs only the first route whose filter matches, and an Err is logged rather than propagated or passed to another handler — so returning an error reports a failure, it does not hand control anywhere else.

Required Methods

fn handle<'life0, 'async_trait>( &'life0 self, ctx: Context, ) -> Pin<Box<dyn Future<Output = BotResult<()>> + Send + 'async_trait>>

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

Processes an incoming update.

Dyn Compatibility

This trait is dyn compatible.

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