Struct SetOutcome 

pub struct SetOutcome {
    pub stored: bool,
    pub previous: Option<Vec<u8>>,
}

What a SET did.

Fields

stored: bool

Whether the value was written. NX, XX and IFEQ can all say no.

previous: Option<Vec<u8>>

The previous value, when GET was asked for and there was one.

Owned, because the record it lived in has been written over by the time this is handed back, and only ever filled in by Keyspace::set. A caller that does not want the copy calls Keyspace::set_with and gets the old value where it still lives, which is what the wire does.
