Enum LinkScope 

pub enum LinkScope {
    Internal,
    External,
}

Whether a link destination addresses something this repository holds, or somewhere outside it.

The distinction is one rule because it is asked in three places that each had their own answer: the site renderer deciding whether a destination can be rewritten to a page it serves, the rendered-site link gate deciding whose uptime a href depends on, and — the reason this is pub rather than private to either — a citation needing to know whether a locator names a work someone else published.

Deliberately closed, and not #[non_exhaustive]

The question is a yes/no one — a destination either names something this repository is expected to contain or it does not — so this is a bool that says which way round it is, and a bool cannot acquire a third value. Any finer distinction anybody wants later (which scheme, which host, whether the path exists) is a different question with a different answer type, not a variant here; making it one would change what every existing arm means.

Variants

Internal

A relative or root-relative path, or a bare #fragment: something this repository is expected to contain.

External

A destination carrying a URL scheme (https:, mailto:, …) or written protocol-relative (//host/…): somebody else’s.
