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 that resolves to BotResult<()>. Returning Ok(()) allows subsequent handlers to run; the dispatcher stops the chain on Err.

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 and returns whether the dispatcher should continue.

Implementations on Foreign Types

impl Handler for Arc<dyn Handler>

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,

Implementors
