Enum Flow 

pub enum Flow {
    Continue,
    Close,
    Block,
    Hold,
}

What the connection should do after a command.

Variants

Continue

Read the next command.

Close

Write what is buffered and then close, which is what QUIT asks for.

Block

Nothing was written and nothing is owed yet.

The client is on the waiter list and its reply comes when a key it named has something in it or when its deadline passes, whichever happens first. Until then the connection stops reading commands, because a client that is waiting for an answer is not a client that has sent another question.

Hold

Nothing was written and the command has not run at all.

The server is paused, so the connection keeps the command it was about to run and runs it again once the pause is over. Everything the client pipelined behind it is kept in the order it arrived, the same way a blocking command keeps it.
