Enum Voice 

pub enum Voice {
    Client,
    Instance,
}

Who says what came of an open.

An invocation started from a desktop entry has no terminal, so the lines it is handed back go nowhere and the person who double-clicked learns nothing — including, on the paths that matter most, that the content file was refused or that it is an executable wearing a document’s name (concept 5.1). An invocation from a shell has a terminal and will print them itself, and an instance that also announced them would say everything twice.

Only the client knows which it is, so the client says. This decides where a message is shown and nothing else: concept 8 calls the front door a control surface, and a field that moves text between two of this tool’s own outputs is not one of its controls.

Variants

Client

The client has somewhere to print, and will.

Instance

The client has not, so the instance speaks through concept 9’s channel.
