Expand description

CallTrait provides convenience methods for the Call struct, which is passed as the first argument to the interface methods.

Examples

For an invalid parameter:

fn test_method(&self, call: &mut Call_TestMethod, testparam: i64) -> varlink::Result<()> {
   match testparam {
       0 ... 100 => {},
       _ => {
           return call.reply_invalid_parameter("testparam".into());
       }
   }
   /* ... */
   Ok(())
}

For not yet implemented methods:

fn test_method_not_implemented(&self,
                              call: &mut Call_TestMethodNotImplemented) -> varlink::Result<()> {
   return call.reply_method_not_implemented("TestMethodNotImplemented".into());
}

Required Methods§

source

fn reply_struct(&mut self, reply: Reply) -> Result<()>

Don’t use this directly. Rather use the standard reply() method.

source

fn set_continues(&mut self, cont: bool)

Set this to true to indicate, that more replies are following.

Examples

fn test_method(&self, call: &mut Call_TestMethod) -> varlink::Result<()> {
     call.set_continues(true);
     call.reply( /* more args*/ )?;
     call.reply( /* more args*/ )?;
     call.reply( /* more args*/ )?;
     call.set_continues(false);
     return call.reply( /* more args*/ );
 }
