Enum PortPolicy 

pub enum PortPolicy<'a> {
    Strict,
    TolerateExcept(&'a BTreeSet<String>),
}

How the loader treats DependencySource::Port declarations from a WorkspaceLoadOptions call.

Variants

Strict

A port dep must be either a port-path directory on disk plus present in ports, or a port = true name present in ports. Anything else surfaces the typed PortDependencyNotPrepared / PortDirectoryMissing diagnostic. Default.

TolerateExcept(&'a BTreeSet<String>)

Tolerate missing port deps except for parent packages whose names appear in this set — the caller’s selected closure. Names in the set still surface the typed diagnostics; names outside the set silently skip the missing edge.

Passing an empty set tolerates every parent (legacy “tolerate-all” behavior); pass a populated set to keep selected packages strict while unselected siblings tolerate.
