Enum ExtractorSelection 

pub enum ExtractorSelection {
    Disabled,
    Ready(DynExtractor),
    NeedsRemoteConfig(&'static str),
}

What a caller must do to honour a requested extraction backend.

Returned by select_extractor, which is the single place that knows which backend names exist. Splitting the answer into these three shapes is what lets the dependency-free backends be selected in any build: only the Self::NeedsRemoteConfig arm requires an optional dependency and the URL and model that go with it, and only that arm’s construction is feature-gated. Deliberately exhaustive (no non_exhaustive): every variant demands caller wiring — construct a backend, ask for configuration, run nothing — and a wildcard arm would silently ignore a new capability instead of failing to compile where it must be handled. Adding a variant is therefore a breaking change, made on purpose, in a minor bump while the crate is 0.x.

Variants

Disabled

No extraction. Tools that need an extractor answer “not configured”.

Ready(DynExtractor)

Ready to use as-is: needs no configuration, no network, no optional dependency. Attach it and the graph builds.

NeedsRemoteConfig(&'static str)

A network-backed backend the caller must build itself, because only the caller knows its URL and model. Carries the backend’s name so the caller can dispatch without re-parsing the string.

Trait Implementations

impl Debug for ExtractorSelection

Hand-written because DynExtractor is a trait object and the trait does not require Debug — a backend is identified by its shape here, never by dumping its innards (an HTTP-backed one holds a URL, and a panic message is not the place for it).

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
