Implementations§

Source§

impl EventListener

Source

pub fn names(&self) -> &[String]

Os nomes dos eventos registrados.

Source

pub fn wait(&mut self, conn: &mut Connection) -> Result<Vec<String>>

Bloqueia até ao menos um dos eventos registrados ser postado, devolvendo os nomes que dispararam. Re-registra automaticamente para a próxima espera (por isso precisa da conexão).

Source

pub fn cancel(self, conn: &mut Connection) -> Result<()>

Cancela o registro no servidor (op_cancel_events) e fecha o canal auxiliar.
