Trait new_tokio_smtp::Cmd

pub trait Cmd: Send + 'static {
    fn check_cmd_availability(
        &self, 
        caps: Option<&EhloData>
    ) -> Result<(), MissingCapabilities>;
    fn exec(self, io: Io) -> ExecFuture;

    fn boxed(self) -> BoxedCmd
    where
        Self: Sized + 'static,
    { ... }
}

Trait implemented by any smtp command

While it is not object safe on itself using cmd.boxed() provides something very similar to trait object.

Required methods

fn check_cmd_availability(
    &self,
    caps: Option<&EhloData>
) -> Result<(), MissingCapabilities>

This method is used to verify if the command can be used for a given connection

fn exec(self, io: Io) -> ExecFuture

Executes this command on the given connection

This method should not be called directly, instead it is called by Connection.send. Which calls this method with two addition:

1. send does use check_cmd_availability, so exec should not do so as it's unnecessary
2. send turns the Io instance the returned future resolves to back into a Connection instance

Provided methods

fn boxed(self) -> BoxedCmd where
    Self: Sized + 'static, 

Turns the command into a BoxedCmd

BoxedCmd isn't a trait object of Cmd but it's similar to it and implements Cmd. Use this if you would normally use a Cmd trait object. (e.g. to but a number of cmd's in a Vec)
