Enum Catalog

Source

pub enum Catalog {
    Unasked,
    Asking,
    Offers(Vec<Offering>),
    Unavailable(SharedString),
}

Expand description

What is known about what a server offers.

Catalog::Offers holding an empty list is an answer; Catalog::Unasked is the absence of a question. The two are separate variants rather than one emptiness because a surface that cannot tell them apart will show the wrong one to somebody who is trying to work out whether their server is broken.

Variants§

§

Unasked

Nobody has asked this server what it offers.

§

Asking

The question is in flight.

§

Offers(Vec<Offering>)

The server answered. An empty list is an answer.

§

Unavailable(SharedString)

The question could not be answered, for the host’s stated reason.
