Enum Before 

pub enum Before {
    Nothing,
    TheSame,
    Different(String),
}

What was at the destination before an install put something there.

Variants

Nothing

Nothing, which is the first install of this target on this machine.

TheSame

A sysroot whose manifest has the same digest, so the install was not needed and nothing was moved. Two rucc versions share a directory for the reason section 13.2 gives, and a second fetch of the same artifact is the ordinary way this happens.

Different(String)

A sysroot with a different digest, which was replaced. The string is the digest that was there, so that whatever reports the install can say what it stood on.
