Expand description

Core trait every handler implements.

Required Methods§

Source

fn name(&self) -> &str

Unique name used for removal from groups.

Source

fn check_update(&self, ctx: &Context) -> bool

Return true if this handler should process the update. Keep it cheap.

Source

fn handle_update<'life0, 'async_trait>( &'life0 self, bot: Bot, ctx: Context, ) -> Pin<Box<dyn Future<Output = HandlerResult> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Run the handler. Return Err(ContinueGroups) or Err(EndGroups) to change dispatch flow.
