Enum Need 

pub enum Need<'value, 'document, N, D, G> {
    Known(ArtifactRef<'value, 'document>),
    Open(Location<N, D, G>),
    Missing,
}

One actual format dependency. Borrowed binary artifacts are queried during the callback and cannot escape it; no DER copy or fingerprint substitutes.

Variants

Known(ArtifactRef<'value, 'document>)

Original known certificate, whole CRL or authenticated basic response.

Open(Location<N, D, G>)

Exact original OtherCertificate/OtherValue catalogue member. The format owner establishes its meaning and agreement before visiting this need.

Missing

A required format-specific value has no matching original open member. Discovery can be complete while incorporated material is missing.
