Enum Unready 

pub enum Unready {
    NotHere(String),
    InstallFailed(String),
}

Why ensure_installed has no runtime to give. A host that starts serve tells the two apart by exit code: a runtime not here, or that cannot run here, is a state of the machine (4); an install that was tried and failed, a download or an unpack, is a failure along the way (1), as a failed pull is.

Variants

NotHere(String)

InstallFailed(String)
